7.2 quake in Baja California today

What scientists are guessing so far:
The fault that triggered the quake was probably located on one of the many faults south of the San Andreas fault, [seismologist Lucy] Jones said. The fault is probably about 40 to 50 miles long, and probably shook for 20 to 30 seconds. The worst shaking would have occurred closest to the fault, said [seismologist Lucy] Jones .

She said scientists would not have enough information to identify the fault until geologists survey the area.

The quake occurred at the junction between two tectonic plates, the Pacific and the North American, that grind against each other through Baja California and California. The quake is probably on a strike-slip fault, which splices through the ground vertically and causes land to move horizontally.

More news is coming in, of course, the "did you feel it?" map is still changing. The quake was only 10 km deep, and I have no doubt we'll hear about more damage than is known so far. As quakes usually are, this one will be another learning experience.

Science communicators are climate heroes

The general public really needs a good bridge between sometimes complicated science and what we are able to assemble into a useful picture. Clear, simple, fact-rich science communication is essential, good science communicators are priceless anymore.

That's why Dan Satterfield is one of my favorite science communicators. He's direct, smart, and really gets to the point, understanding what his readers need filled in. His most recent blog post really makes that clear to me. Dan goes step by step through not only the reasons why climate change is now scientific reality (with some amazement at the TV weather people who dismiss it as myth), but he also insists its the TV meteorologist's obligation to sort it out for the watchers, for the folks at home whose only exposure to real scientists and balanced science throughout the day might be what they get from their trusty TV weatherguy.

Dan's also just plain good folks. But he's good folks with a sharp mind, and the kind of understanding of his audience (both for his blog, and on TV in Alabama) that teaches rather than preaches, that informs rather than lambasts, that gets the point across in the way we need right now.

He's the kind of science communicator that we can point at as part of the solution to the problem. When you hear people saying, "If only we could communicate science to the masses," point them to Dan's blog, and say, "You mean, like that?"

frazil ice in Yosemite National Park

Steven Bumgardner, who produces Yosemite Nature Notes for the National Park Service, shot some video of "frazil ice" on the Merced River in the park this week, as a cold early spring storm moved across California.



I'd never heard of frazil ice before. Now, because I must look things up compulsively, I'm learning about it. Wikipedia says, "Frazil ice is a collection of loose, randomly oriented needle-shaped ice crystals in water. It resembles slush...," which probably explains why I'm imagining margaritas. And Hajo Eicken at the Geophysical Institute at the University of Alaska, Fairbanks, says
The word frazil means fine spicules or blobs, which gracefully describes the morphology of the crystal. Sea ice growth always begins with frazil ice production, the only true dendritic ice growth phase. Active convection aids sensible heat transport at the ocean surface, thereby super cooling the water and allowing dendritic growth of ice crystals.
This is so cool. Spicules and blobs. Scientific terminology rocks. ("Dendritic," of course, means it's like branches of a tree, like drainage in a river delta, or the shape of a neuron.)

The waterfalls of Yosemite must be delightful just now.

The shaping of the Great Lakes, in an hour

The History Channel's new series, "How the Earth was Made," is mostly just scientific enough for me today, as I'm fighting a low fever, and wanted to stare at something educational without spraining too many neurons. Today I sat down with Hulu and watched an episode about the creation of the Great Lakes.



I knew some of it, such as the glacial history, but hadn't known about the igneous origins of the floor beneath Superior and Ontario. The series is presented in steps, giving evidence for theories (with a bit of the History Channel's typical "but that's not all" and "there's more they didn't know," and "but still, mystery remained" drama), then before each ad, recapping the bits. I appreciated those, it helped me knit the story in stages before going on to the next chapter in the story.

As it turns out, I had no idea how fast Niagara Falls was receding. Do you know? What would you guess? Watch the show and see. I was a tad stunned.

(If the Hulu.com video expires, you can find the video for sale at the History Channel website, with a few clips and full episodes still available.)

Do I corrupt my friends or do they corrupt me?



My friend Andy sent me this IM conversation with our friend Paul:
Paul: what is the tensile strength of ROCK AND ROLL quick I need to build this city on it
Andy: The tensile strength of ROCK AND ROLL isn't relevant. Unless you planned to build this city out of it.
Andy: Since you want to build the city *on* Rock and Roll, you'd want to know it's ductility.
Andy: The ductility determines how big the buildings can be without risking sinkage. also, in earthquake zones, low-ductility Rock and Roll would lead to liquifaction, damaging entire regions of the city.

I might be weird, but my friends might be weirder.

Simple Pleasures

Anna's hummingbird (Calypte anna) in flight .... 1 of 2
I just had one of my best bird experiences ever.

I've been paying attention to birds since I was pretty young, but I rarely go out and seek the rare ones. I tend to marvel at what's nearby.

I'm very happy that I got to see a Long-tailed Jaeger once, when it was lost in Mono County, and I was very excited when my husband (decidedly not "a birder") identified a Heerman's Gull along a path a bit west of Monterey Bay Aquarium. But mostly, I revel in the air-coasting of Turkey Vultures, and the way the American Robins fill my yard every March, and the markings of the hundreds of Cedar Waxwings in our local trees (they have a wheezy, tuneless song that is irrelevant given their gorgeous fancy clothes).

I like birds for learning about what they do. I like being able to spot a Western Scrub-jay without glasses on (my glasses, not the jay's) from the way its short swooping glides bring it down from a tree, and I like knowing that we have Black Phoebes because we're near a stream, and they eat bugs (they're at the local dog park for the same reason: flies love those trash cans!), and I like knowing that though the Cooper's Hawks in the neighborhood might be after our chickens, the Red-shouldered Hawks would prefer our pocket gophers. Our garden is grateful for Red-shouldered Hawks.

Today's event was both wonderful for its commonness and what it told me about basic bird behavior, and exhilarating for its sheer wonderfulness.

I was out in the driveway collecting mail, and as usual, our rooster jumped up onto the chicken pen's gate to let me know he was Still The Man. He crowed, and I said "Hi, Rooster," then over my head, in the tulip magnolia tree, a male Anna's Hummingbird began his squeaky territorial chirping. It's fully spring here, so the hummingbirds are nesting, and Anna's Hummingbirds are the kings of the "Gerroff my LAWN!" attitude. (I remember reading an article years ago in Smithsonian magazine describing the hummingbird migration in Arizona. One ranger at a state park told a visitor that if hummingbirds were the size of ravens, it would be unsafe to go outside. When a visitor exclaimed about the belligerent males, "They're so sweet, and so tiny!" he replied, "Yes ma'am, they are tiny.") I noted to myself that the rooster and the hummingbird (also a rooster, in his tiny way) were doing the exact same thing, crowing at the entire world to say that they were indeed The Man.

I couldn't see the hummingbird (no glasses on, and he was in a tree with hummingbird-sized leaves and blossoms), but when he flew over to another tree and began to chirp there, he was obvious. The sun was behind me, and as he moved slightly on his stick-end, he flashed with an almost inorganic magenta, the refractive feathers on his head and gorget throwing photons back at me. And then in a flash, he went up, up, and vanished. I kept my eyes on him as long as I could, but he was, it seemed, nearing escape velocity.

Anna's hummingbirds have the most amazing behavior. Sometimes they swoop down in huge, steep parabolas, making a sort of … ding? bing? musical pop? at the bottom of the dive. They'll fly up, out of sight, then down. I've seen them do this before, from slightly to the side, watched them form the parabola shape. But this time it wasn't quite overhead, I craned my neck up, staring directly at the sky, and the bird quickly became a dot, then disappeared. I knew he had to be diving in a moment, but where?

Then bam! or rather BING! Right over my face! The bugger had dived at my head as I stared and I never saw him. They are very, very fast. From the sound's direction and volume and the sudden bzzt! of wings, I estimate that the vertex of his dive was 2 to 3 feet over my head, and that's close enough.

My heart pounded, I clasped my hands to my chest and said, "Oh BOY!" The little hummingbird was up again, and gone.

It's quite easy to make me happy, really.

Imagine being terrified of tiny tremors, for good reason

The recent 5.6 earthquake in Cuba brought down a house in Haiti, and killed two people (at least, so far).



In a country as shaky with aftershocks as Haiti has been, and recent torrential rains making life miserable for people who live under tarps, and still live in gullies (as they have for a long time), imagine if every time the earth shook just a little, you feared for your life. The people under tarps are wetter, but perhaps safer.

Army Street, San Francisco

This is the sort of thing that eats my brain. Someone on livejournal asked where Army Street got its name. It's been 15 years since the name was changed to Cesar Chavez, but a lot of locals still think of it as Army Street, just as there are parts of Martin Luther King Bl. in the east bay that I'll always call Grove Street, just because I was living near there, or knew someone who lived near there, or shopped there, when it was Grove. I have nothing against Chavez or King, it's just that I'm old, and my brain settles into patterns.

At any rate: Now I'll be digging half the day looking for the origins of the name Army Street, because it's the sort of thing I can't let go, and I have things to do, and don't have time.

If you know, please help out here, or on livejournal at the link.

Thanks!


Edited to add:

Found by @silvercrone on twitter:

"As for Army, Loewenstein says it was named by John and Robert Horner, who bought two ranches in the area for $200,000. They named the street to honor the military. There was also a Navy Street, but it did not survive. Its name was changed to a number."

So far, the only relevant Horners I've found were in San Francisco in the 1860s. They did have ranchos, were they the Horners? Probably. Still searching.

Washing into the sea

Madagascar is falling apart geologically and biologically.

Today, Soichi Noguchi posted a gorgeous picture of the mouth of a river in Madagascar, pouring mud into the sea with a design like an abstract painting:

FIRE! Madagaskar. Almost like an oil painting. on Twitpic

Sadly, that mud is flowing off the hillsides with every rainstorm, every one of Madagascar's not-infrequent cyclone hits, and blows off with the wind. Deforestation began in Madagascar with the first European colonization, and the demand for exotic wood (or any wood, eventually), and continued as slopes were cleared for agriculture. Between the general population of Madagascar, with people simply trying to get enough to eat, and shelter, and work, and the corporations driving the agriculture, it will be amazing if Madagascar can keep from dying, biologically, before any sort of control or balance is found.

To drink forever alongside Odin

I can't always figure out where Geography ends. Does it include our atmosphere? I think so. Magnetosphere? Why not?



Of course, astronomy fascinates me, too.

At any rate, the auroras are clearly in the zone where astronomy and geography overlap.

Astrospace Now has a great podcast discussing folklore about the auroras.

I've only seen an aurora once, and it was an Aurora Australis. I was at only 32.7 degrees south latitude, in South Australia -- very far north to see them. They oscillated and shimmered like a bright green gossamer curtain. I hope to see the Aurora Borealis this coming spring, when I'll be in Alaska.

... but not as we know it


Mono lakeshore
Originally uploaded by marymactavish.
Felisa Wolfe-Simon, a geobiologist, thinks Mono Lake may host "...alien life forms, or 'weird life'." She is investigating whether, in the mud or water, there live microbes "whose biological make-up is so fundamentally different from that of any known life on Earth that it may provide proof of a shadow biosphere."

Wow.

I love the Mono Lake basin because it's stunning and fascinating.

The Sierra Nevada rise along its western side.

Panum Crater, to the south, is a small volcanic cone a few hundred years old. When you hike up into it, first you walk over crunchy pumice, then over pieces of obsidian that tinkle underfoot like broken glass, making the thought of a stumble slightly nerve-wracking.

I once saw a Long-tailed Jaeger in a freshwater pond just north of Mono Lake. It's a pelagic bird that was lost ... or interested. Many species of bird feed on the brine flies at the edge of the lake. Eighty-five percent of California Gulls (the species, not the geographically-placed) breed here.

And Mono Lake plays an important role in the history of the environmental movement, its healthy future being the impetus for the Mono Lake Committee, one of the most effective and inclusive grassroots environmental movements in California.

But now, the possibility of parallel evolution? arsenic-based life? Mono Lake just gets cooler.

At least the birds got a few extra mud-critters for lunch

This covers the first two-thirds or so of a tsunami surge cycle at Point Loma, in San Diego. A small tsunami sloshed around the entire Pacific Ocean on February 27, 2010, in response to an 8.8 earthquake in Chile.

As much as that this video is nearly ten minutes long, I wish it had been longer. I'm not sure I'd want it edited, either -- I like the everydayness of it, the way people are talking to each other, and their wonder at the water.

I'm working on a bigger post about Chile, which I'll post in 12 hours or so.

The Mimic Octopus


Mimic Octopus
Originally uploaded by Daniel, Daniel Kwok.
Like everyone, I sometimes have days on which I do little but watch octopus videos:



This species, the Indonesian mimic octopus, was just discovered twelve years ago. It is fabulous.



It's known to mimic at least 13 different animals or corals, some of them deadly poisonous, though scientists admit they don't always know what they're seeing.





They're lost due to habitat degradation, fishing bycatch, recently even the pet industry.



It saddens and sometimes horrifies me that we can be doing such damage to species that weren't identified by scientists until our current crop of high school students was first learning to read.



I don't eat octopus, and I do what I can to help protect its habitat and the creatures in it. Biodiversity is essential, no species is completely expendable, but octopuses are just too damned cool to lose.

Frankly, I'm a little disappointed

Matt Rosenberg pointed out on twitter that the Einstein geography quote I posted (which I'd found on a university's geography department homepage, so trusted without thinking) was debunked: ".... this quote was actually written by Duane F. Marble, Professor of Geography at Ohio State University." The rest of the story is at the link.

I'm a little disappointed. It would have been an awesome thing for Einstein to have said.

Wallpapering with rocks and dirt

A huge chunk of my time for the past couple of days has been spent reinstalling Windows. It turns out that one can save a lot of time doing it right the first time --who knew? But I have a cranky old laptop, and only moderate computer skills (and a life, with other things to do), so I've been stuck with my old Treo for internet use for awhile.

While I was looking for interesting replacement wallpaper (eagerly anticipating a switch either to a Mac or to Windows 7, so I can rotate wallpaper -- decisiveness isn't my forte, I'd rather rotate nice wallpaper than have to decide) I stumbled on this neat blog I'd never seen before:
Geological Musings in the Taconic Mountains and today's relevant post, Geology Desktop Images.

I haven't yet poked around on it (still setting up my laptop) but will as soon as I've truly up and running.

Snowing on blog ideas, or something

The internet is filling up with time-lapse snow photos from the east coast!



(Details on click through.)

I've got a whole list of geographile-seeds on my desktop here, and one hard post I'm working on, I want to explain the difference between climate and weather, and how climate change (or even global warming, gasp) could explain heavy-snow winters. I'm also working on the geography of the setting of one of my favorite book series, and exploring the relationship between HAARP and the Haiti quake - or the lack thereof.

What do you want to read about?

Manzanita mandala


Manzanita
Originally uploaded by robherr.
I've written before about how much I love manzanita.

I want to learn to discern the various California species, but Pete Veilleux over at East Bay Wilds, who really knows his local native stuff, says it's a difficult task.

Among my classes this term are a couple or three that focus on local natural history. That should help.

Martin pointed out this gorgeous circle of manzanita leaves from Rob Herr, at Flickr. (He granted me permission to use the photo, it's not in the creative commons realm.)

The leaves are so beautiful and special. They're sclerophyllic, tough and a little leathery, to survive the hot, dry summers of their western habitats. The leaves chemically change soil to make it harder for competing plants to grow. And the colors, oh: they start so delicately green, and toughen to a darker green, turn reddish, then before they're gone, it's as if they self-immolate, without flames, they just dry and blacken. (They sometimes fall off before this stage, too, but it's weird, like someone's lit them.)

Their angle on the plant maximizes sun exposure when the sun is less direct and drying, in the morning and late afternoon, but minimizes it at midday, conserving moisture.

I love manzanita. Later, I'll write about the fire ecology around it and chaparral, and its magical bark, and what I want to do with the wood.

Howard Zinn was a great historian. I encountered him in high school, and if he did nothing else for me, he encouraged me not to take everything my textbooks said as the whole truth and end of the story, but to ask questions and think beyond curriculum. I've applied that to most of what I've read in academia and the media in the decades since.

Lately I've been wanting to know more about who's reading Geographile, and why.
I don't get a lot of comments, nor do I troll for them. I'd like to make the blog a little more interactive, but I avoid all those "get more comments" web pages and similar, I'm mostly here for myself. But I know there are readers.

I don't use site metrics. I don't beg for comments. So how do I find out who's here?

I must not have had my creativity hat on, because when I saw this Coyote Crossing post, it was so obvious.

Chris said:
If you’ve been reading Coyote Crossing for a while and never said anything, or even i this is the first time you’ve been here, consider this your formal invitation to introduce yourself, say hello, offer advice or complaints, or just generally mark a little bit of territory.

Go ahead and substitute Geographile for Coyote Crossing, except, in the marking territory category, I must say: Please don't pee on my blog. Thank you.

And while you're at it, check out Coyote Crossing, too. It's insightful, full of good information, and just plain interesting.

ferocious weather

Well - not really ferocious. We just so rarely get tornados, that when we do, it's a bit startling.



Our tornados in California are almost never as high as 2 on the Fujita scale, and are usually 0 or 1. This one touched down, but well away from where it could do damage.

I keep thinking, "Now I'm going to write about this wacky week of weather," but then we keep having more days of it, and I think, "As soon as it's done ..." Rain is in the forecast, but it looks like the wildness is calming down. Perhaps it's time.

Haiti - hoping for recovery, in context


Peacekeeping - MINUSTAH
Originally uploaded by UNDP Global.
When I was little, one of my favorite books was The Stone*. I don't remember the details of it, I just remember the imagery, learning about Heart of Palm, and children's relationships with elders, and the life of a boy in what seemed to me a poor, but idyllic, countryside.

Mind you, it was set back when Haiti still had trees, but still: Life there was anything but as idyllic as the book showed, even then.

The misery wasn't shared in a children's novel, of course. The book made me want to live in Haiti one day. I became interested in French, and more than that in Creole. I imagined wandering jungles and listening to birds sing.



I only recently realized how much that book became most of my rose-colored knowledge about Haiti.

In adulthood, I've known that people thought it worthwhile to float hundreds of miles across open water in rafts to escape Haiti. I've known about Papa Doc and Baby Doc being horrible, fearsome dictators, and that the US somehow propped them up, but without detail.

I've known that Port-au-Prince was desperately crowded and poor,



that slums in Haiti and many towns have open gutters running down the middle of the road to carry raw sewage, and that children there were desperately hungry.



But I realize now with some shame that I had no idea of what the history was really like, Haiti's ancient legacy of debt, and how, between historically oppressive France, and the callous policies of the US, and what seems to be like near-disdain from the IMF, Haiti hasn't been able to get a break at all.

Add onto that its recent hurricanes, its overpopulation and environmental exploitation leading to deforestation and mud sliding, and now, the unlocking of a 200-year-old fault bringing shoddily-built Port-au-Prince to its knees in a pile of concrete dust and bodies, and I wonder how - or whether - they'll recover from their current situation.

My friend Meredith posted a link to a story with a brief history of Haiti, by Alex von Tunzelmann, from the London Sunday Times, May 17, 2009.
Just why is Haiti in such a dire situation, so much worse than any other country in the Americas, and as bad as anywhere on Earth? Some blame the United Nations. Some blame the Americans. Some have theories about the collision of global warming with global capitalism. All are careful to point out that the Haitian elite deserves its reputation for being greedy, negligent and kleptocratic. "I think the Haitian people have been made to suffer by God," Wilbert, a teacher, tells me, “but the time will come soon when we will be rewarded with Heaven."

There's a full summary of Haitian history at that link. Please click through and read it when you have a minute. In Wilbert's words, I hear Pat Robertson giggling. Pathetic slime rat.

I know Haiti needs help now more than ever before (except, perhaps, when they were trying to get out from under the French initially - what might be different now?) but I have no idea what we need to do. I'd start by saying that the US and other countries need to seriously consider more refugee status for Haitians. We need to help within the country more, but they've been a black hole for charity dollars in the past, with their kleptocracy and corruption. Doctors Without Borders, Oxfam, the smaller organizations are doing what they can with non-financial help, but in that system, how much can they do?

I'm overwhelmed at the thought. "How to fix it" is not my area of expertise, or they'd have called me long ago. Does anyone really know?

One thing I'm sure of: Knowledge is power. Learning about the history of countries like Haiti (and Iraq, and Israel/Palestine, and Laos, and Bolivia, and even the US) correctly, unsanitized, places current problems in context, so that solutions can be built from a base of fact and strength, rather than on a pile of rubble. We need to make sure other people see and read that story, and others like it.

*Searching now, I can't find The Stone. I don't remember who wrote it. It was about a boy named, I think, Peter or Pierre, and I think he lived with his grandmother, and loggers were cutting the palms, killing them, killing their hearts - so heart of palm, which was loved and precious, could not be harvested.

Port au Prince from the hills above it, today



How terrifying to see from above ... but far worse from the streets below.

sfgate.com has a great list of organizations who need your help so that they can help the people of Haiti. It looks like Doctors Without Borders lost their surgical facilities - and Haiti needs them right now. They're on the list. UNICEF needs you, too, as does the Red Cross.

Haiti is already the most impoverished nation in the western hemisphere, and hasn't yet recovered from last year's hurricanes, let alone the decades of political upheaval and violence. There's only so much we can do ... but that's better than nothing.

Finished Back Piece

I've been going to get a tattoo for ages, and I've only wanted Marie Wadman at Diving Swallow to do it. She's expensive, but VERY GOOD and sympatico with what I want.

I'd been planning on Douglas irises and/or California poppies, two of my favorite wildflowers. But I'm also in love with manzanita. One of my goals this year is to learn to discern each species of manzanita in the greater bay area.

I want California native plants because this is home, where my parents grew up, and I grew up, and my Mom was born, and Grandpa was born, and his parents were born ... back to the 1850s. And we're not beach people or mountain people, we're coastal hills people and sagebrush people and foothills people. My bones are partially made of manzanita wood, I think.

Eventually, my only wishlist item will be a link to a jar where folks can throw pennies at a tattoo fund. Then, when it's full, I'll contact Marie as per her instructions (ping her in fall, she'll get back to you later as she fills up her entire coming year's calendar) and plan my first tattoo.

(Here's the whole manzanita tattoo set from savor_soaps on flickr. I love this.)

Or maybe they're going to Oregon because it's what Californians do


Curious Sea Lion
Originally uploaded by Dave Schumaker.
I like to write Geographile posts that, if not brief, are either heartfelt and eloquent, or well-researched. Brief ones can be neither. However, this one also is neither. It is ranty and annoyed.

I'm recovering from the flu, and what I want to do, really, is to go play flash games and have a beer, or maybe have another Sudafed (the real stuff) and go to bed.

But instead, there was this earthquake today, which was exciting. And besides all the Jesus Is Coming and similar posts on twitter, the bad science started coming out.

See, last October, the ubiquitous, numerous, smelly, but cute California sea lions at Pier 39 in San Francisco started leaving the area. Then more left, and soon, people were wondering what had become of our sea lions, which aren't historically massed there, but have been as of the past few years.

Within the past couple of weeks, they were found, up with the Steller sea lions and other marine mammals along the Oregon Coast, and at Sea Lion Caves, perhaps due to shifting temperatures, those perhaps due to our currently strengthening El Niño pattern, because that's where their food went. (Yes, there's still a lot of "perhaps," but this was a puzzle until recently, and is coming together.)
.
And of course, because it seemed "suddenly," folks on Twitter are saying, "They knew the quake was coming." (At least one of these twitterers might even be from the bay area or elsewhere in earthquake country, or perhaps sea lion country. Or not.)

But this is not sudden, and there are explanations:

1) The sea lions started leaving in October.
2) Recent, pre-today research suggests that their being found in SW Oregon reflects temperature changes in the ocean off the coasts of California and Oregon, and the food the sea lions prefer is following the temperatures they like. The sea lions are following fish. (Some aren't. Some seem to be hanging out at the Farralons for squid. But many went to the waters off the coast of SW Oregon for fish.)



Now here's the thing:

According to Google maps, from Florence, Oregon, where Sea Lion Caves is, to Ferndale, California, the nearest town to today's quake epicenter, is 285 miles. From San Francisco to Ferndale is 262 miles, by straighter roads. So let's call the quake area halfway in between there. (Yes, I know the sea lions don't drive. But I'm ballparking things here.)

Why would marine mammals leave in October (and later, but still) to swim through where a quake is coming, and end up just as far on the other side ... because they knew a quake was coming?

sealionquake1

It's not like I expect sea lions to have logic, but c'mon: Why? Why not go, oh, to Santa Barbara, the other direction? Why go to all that effort to end up the same distance from the quake anyhow?

And why leave San Francisco when today's quake was barely felt at all there? It wouldn't gain them any advantage.

quakesealion2

Folks are saying, "Animals do strange things." Sure. Sometimes they do. But if you're going to make a wacky connection, at least come up with a good enough story to support it.

Dear people who were kind enough to discuss this with me on twitter today:
I don't mean to be totally dissing you. I am open-minded about, say, that there are aspects of quakes that animals can sense but we don't, and there are noises they can hear that we can't. But look: The idea that sea lions would leave the San Francisco area for Oregon, passing through an area where a quake is going to happen weeks in the future, to end up the same distance on the other side, when there's no good reason for sea lions to care, makes no sense on any level, not even if I were to open my mind so far my brain falls right out.

Arctostaphylos pajaroensis 'Warren Roberts' - Warren Roberts Pajaro Manzanita

One of my goals this year is to learn to discern every single manzanita species within a couple of hours of my house. They're different, they fit different niches. They're mostly sclerophylls, and healthiest with wildfire every couple of decades. They control the chemistry underneath them for their own best health. They have the most beautiful wood, and the most fairy-like little flowers, and I am in love with them. They are one of the plants that screams "California" to me, the California I grew up with and love.

early geography


rainCIMG8739
Originally uploaded by marymactavish.
When I was at my youngest, the scale of the world, and what went on over the earth, never occurred to me. I fell asleep on long car trips, so I thought we lived relatively near the bay area, as I always woke up as we crossed the Carquinez Strait. I actually remember many of the various stages of geographic awareness I passed.

When we got air conditioning in our car, and didn't have to drive down the valley at 2 am in the roasting summertime, I learned how far away we were from the bay area, as I was awake for the ride.

And Robert Louis Stephenson taught me to think about what was going on elsewhere, in terms of shared experience. Steady, cold rain like today's reminds me of his poem, "Rain." It's so simple:

THE RAIN is raining all around,
It falls on field and tree,
It rains on the umbrellas here,
And on the ships at sea.



Oddly, re-reading that, I notice that I remembered it differently. Until now, I remembered, "It rains on houses in Japan/And on the ships at sea." I wonder why. Was I looking at pictures or reading books about Japan, then? About houses or umbrellas in Japan?

Hm.

This sort of thing, though, colored my geographic learning, and I think it's valuable in any child's learning, to have literature that isn't all about morals and lessons, but also about images, and places, and shared experience, and how things were different back then, and about how we're not the only people in the world, and our experience is not the only experience, and that there are things we will all share, and that there are things that we might never relate to.

The Universe, and the Tibetan Plateau

This new video from the American Museum of Natural History is making the rounds. It's a stunning digital visualization of the known universe with proper sizes, distances, scales. I'm not sure exactly how they increase speed of change. It definitely changes, as it takes a few seconds to travel a few light seconds, then not long after, a few seconds to travel many light years, or a few million light years. It had to be thus, but I did lose a sense of scale eventually, even with the incredible illustrations.

I had no idea, for instance, how much completely unmapped space there is. Why is that? I can see it being hard to map past the center of the Milky Way, but couldn't tell in which directions we're yet unmapped, and why -- could be be that hard to map in the opposite direction from the center? Are the stars densely packed that direction, for far enough to make it opaque for us?



Of the whole video, though, my favorite part was tipping past the Himalaya to see the lakes of the Tibetan Plateau. I had no idea how lake-rich the area is. I knew that it was sparsely populated, that big quakes there can go almost unreported except by instruments, that there are thousands of square miles with no roads. But the lakes just caught my attention: Look at all this gorgeous water. What's it like there? Who lives there? What do they do?

It turns out google and flickr both had answers for me.

lunacy, really

According to Phil Plait, at least 90% of all murders happen within a week of either the new moon (like right this minute) or the full moon.

Amazing, really, when you think about it.

Geologists rock!

Might be that a certain road crew should take geologist Vanessa Bateman out for coffee.

The video gets interesting at about 1:00ish.



I'm really not sure I wouldn't have flipped the hell out, watching this. Then I'd have asked Bateman to follow me around and be my body guard.

The Anthropology Song

Anthropology is close enough to cultural geography to count, for me. I like this song enough that I played it in the background while I did other things a few times today.

What if Earth had rings like Saturn?



I don't want to interrupt the loveliness of this idea, but there are bits from the video and the comments that I want to note:

Someone commented that this might make places under the rings where it was permanently dark. But because the earth is tilted on its axis and the sun appears to move north and south through the sky seasonally, so would the shadow move. But it's likely some places (the equator, generally everywhere between the tropics) would get some level of shade from the rings. The layer is very thin; aside from under the rings at equinox, there would be plenty of bright sun. Would there be enough insolation change to affect climate? Probably. But given the scenario, I expect the earth would have evolved this way, it's not like it would be a change from how things are now.

The person who made the animation seems to have designed it for equinox. Seasonal variations aren't addressed at all.

The theoreticals (e.g. one commenter's note that this would affect satellites) are irrelevant to me: It's beautiful.

Accra - A C C R A

I don't know the capital of every country in the world, nor do I think I *should* - but this is still fun:



When I was little, and couldn't sleep, Mom suggested I list every single state in the US, alphabetically. If I ever realized I'd missed one, I had to go back and start from the beginning. I don't think I made it to Wyoming.

I found myself, as I passed San Bruno Mountain today, where the endangered Mission Blue butterfly lives, "There are Mission Blues on San Bruno Mountain, but the California dogface butterfly is our state butterfly. Why do I know that? I don't know. I just do."

It's the sort of useless thing that helps me paint a picture of the world when people talk about it. It's a piece of the whole puzzle.

How cool is that? That is very cool.

We're fostering a tiny puppy, switching the garden over into fall mode, trying to get our house in order, and I'm finishing a semester at school. This is Geography Awareness Week, and I think there will be a post about that before the week is up.

sense of place - Oakland Hills Fire


Oakland Hills Fire -- after
Originally uploaded by marymactavish.
For some reason, as I go through my old photos, the fire photos are really affecting me. Even before I noticed them in my stack of "photos to scan," I was noticing again how the hills have grown up thicker with eucalyptus than before, and the plan to places houses farther apart and make roads wider is barely there. And I might be wrong, but I think that Oakland never did get around to making its fire hydrants compatible with the hoses of surrounding towns' fire departments.

But anyway: I'm thinking of it, eighteen years later.

Look! Up in the sky! It's a bird! It's a plane!

It's the moon! It's meteors!



Pretty much everyone knows that I have a broad definition of "geography," right? Usually, if I can see it from earth, or if what happens there is directly relevant to earth, I'll often decide it counts. For awhile, I pondered having a day a week set aside for related sciences, but I've mostly given that up. If I post them here, I'll find a way to make them geography-relevant.

But this trailer is about an event that involves people on the ground looking at things relatively close to us, including within our atmosphere, so I think it's all about geography. Check it out. It's a lot of fun.

Why did Georgia flood so badly this year?

This guy talks about a couple of reasons quite clearly, if a little over-excitedly. He makes good points. There are probably hmore reasons, but these are the jist.



(About his first argument: Fall flooding like this was pretty much predicted by models.)

Feed the child


Me and Paula, 1975
Originally uploaded by marymactavish.
I grew up in a 1950s housing development, thick with oaks and chaparral, on the edge of fields and oak woodlands, near the banks of Churn Creek. Mom let us dig in the yard – I loved my real metal Tonka trucks and old silverware digging tools – and we camped in rural Shasta County several times a year. In the hottest months, when the house was too hot to sleep in at night, we slept on the back lawn, and watched meteors fly overhead, while Mom taught us the names of constellations.

I learned to swim in creeks and lakes. I peeled endless acorns in my attempts to make acorn mush under trees while friends had tea parties in their bedrooms. I used my magnifying glass to set small piles of oak leaves on fire in my driveway, knowing better than to try that out in the woods.

When I was little, we were allowed to run around the woods (some of it has become a giant church complex, some is now protected as park) and nearby fields. I think I was 7 or 8, just old enough for my mother to append “bring your sister” to my requests to go play “in the fields,” as we called them. My sister wasn’t yet in kindergarten, and hauling her along was like dragging an anvil behind me as I ran off to the trails and creekside on the road to adventure.

Mom taught us how to avoid rattlesnakes and poison oak (we didn’t assume there were mountain lions around, but there had to be, we were right on the edge of town), and told us to be home before dusk, then sent us out to play. There was really nothing we were forbidden except to go into the rain culvert where Churn Creek went under Highway 44, in case of flash flood – so we did, of course, and would stand under the stormwater grates and listen to the roar of cars and trucks overhead, reveling in the danger. I didn’t climb trees, but the live oaks and black oaks often had multiple lanes of commuting black ants, and the gray pines were sticky with sap, and weren’t good climbing trees.

Instead, we collected sticks and branches and crunchy, prickly fallen leaves and wove forts not much bigger than our bodies. After intense summer thunderstorms, we’d go out to where the boys on their bikes had worn ruts over the dead grass and hard dirt near the creek, and slide down the mud-slick ramps on our bottoms. We had church clothing, school clothing, play clothing, and “mud clothing,” the bottom of the barrel, as Shasta County’s iron-rich soils leave permanent red tint on any clothing that touches it when it’s wet.

We picked wildflowers in the spring, and on the first of May, we made paper baskets, then filled them with brodaeia and shooting stars and lupine and wilting poppies and hung them on neighbors’ doorknobs, ringing the bell, then running away. We knew the names of most of the flowers – Mom called everything by name -- but she called all the brodaeia species “blue dick,” and called all the hummingbirds “ruby-throated” because in our basic birding guide, that was the only hummingbird with a red throat. (Anna’s weren’t in the book, and weren’t part of Mom’s Modoc County childhood, as they’ve only gradually moved north with human population.) Turkey vultures were “buzzards.” Everything had a name, though they weren’t always accurate names. We called gray pines “digger pines,” as that was their name then. We knew they were named after the foothill native people who were called “Digger Indians,” but even though my grandmother was an advocate for and sympathetic friend of the Pit River and Maidu people, it never occurred to any of us that “digger” was a racist euphemism.

One of my iconic memories that defines what gave root to my adult curiosity came on a late spring day, on one of the several trips to Burney Falls and Mount Lassen that we took every year. Redding was much smaller, then, and roads in the surrounding hills were often quiet. We were somewhere up near Kings Creek or Hat Creek, and there were turkey vultures rising on the morning thermals. They seemed to be doing their morning cruise more than looking for food, so Mom pulled over. “Get out of the car,” she told one of my older sisters. “Lie down in the middle of the road.”

Terry’s mouth fell open, and she shrieked, “WHAT?”

“Just lie down.”

“I’ll get run over!”

“I’m watching, I’ll tell you whether a car is coming.”

These days, ornithologists know that turkey vultures hunt by smell, not sight, but in the sixties, most people hadn’t learned that. My sister lay in the middle of the road for awhile – a minute, or five minutes, I was young – then leaped up to brush her clothes off and yell at Mom for risking her vulnerable child’s life.

The vulture hadn’t landed, no traffic had come by.

Had a vulture landed, would Mom have allowed it to pick out Terry’s eyes? Would she have scared it off? I might never know. Mom was that kind of woman.

This is the story that I most vividly remember, about Mom’s fascination with nature, and how she fed it to her children, but it’s one of many. Her willingness to live in nature, not as a spectator, but as an active participant, flowed onto and into me along with her milk and her singing when she was happy, and later her taste for ginger and marzipan.

They really don't make flags like they used to

Wikipedia says: "The Benin Empire or Edo Empire (1440-1897) was a pre-colonial African state of modern Nigeria. It is not to be confused with the modern-day country called Benin." In Nigeria, Benin City still sits to mark the region, a central part of the slave-trading region of the 17th century.



I want to learn more of the kinds of world history I missed in middle and high school, either because it just wasn't taught (where do kids learn about the Benin Empire in high school history?) or because in all my moving around (five high schools, really and truly) in my youth, I missed out on some curriculum.

This is the sort of thing I've missed.

Nothing's where you think it is



"What do maps have to do with social equality, you ask?"

The good doctor (don't let me say "phlox" here) has a point. Size on a map matters, kids grow up seeing disproportionate sizes, and perhaps, attributing disproportionate values, even unconsciously. I think that as they learn mapping, learning about different projections, and the reasons for them, will continue to be important.

When I lived in Australia, I had a "corrective map of the world."

How much do these things matter? Why?

And I did crack up at the video clip. A lot.

Scientific literacy for girls - it's like seeding the future

Maybe I just cry easily, but this video from the National Science Foundation pushed me over into tears:



I'm saddened when I listen to teenagers, or even adults, or read what they've written online, and it smacks of scientific illiteracy, or even scientific ambivalence.

A couple of years ago, I took a college-level class in which we studied, among other things, the effect of the full moon on behavior. Study after study we examined showed that even when, for example, emergency room staff or police officers say people behave more wildly during a full moon, statistics -- based on arrests, ER visits, psych ward incidents, and other apparent behavior measures -- show that there really is no causal relationship between behavior and the phase of the moon. (In the few small studies that show some minor correlation, it can be explained elsehow, e.g. the full moon only increased wild behavior when the weather was also warm and folks were hanging out on the street more.) But after this investigation, students still insisted that no matter what science suggested, they knew that the full moon affects behavior because their nieces and nephews threw more tantrums, or they saw more chaos on the job, or whatever. Science was irrelevant. They didn't seem to get how it worked.

The kids in this program are excited about science. The topic at hand is astronomy, but they're not all interested in that, specifically. Some want to be doctors, one says she wants to be a marine biologist. Some might even end up being teachers, or stay-at-home parents, or captain ferries that cross the bay. But they're learning, they're excited about learning, and they're excited about science. This is priceless. These are the kids we need growing up into our future, and making it go.

I'm not sure why I cried when I read this. Maybe it's because these are kids mostly from Oakland, and mostly African-American, and the high school dropout rate in Oakland's phenomenal, especially within the African-American community. Maybe it's because a female, African-American astronomer is part of their worldview now. Maybe it's because these are girls, and the adults working with them seem so much to care that they grow up with positive, science-related educational experiences. Maybe it's because these are kids and need a positive science background, and many public schools can be a hard place to get that these days, and the Girl Scouts and Chabot Space and Science Center and the other people and organizations behind this program are offering it to them.

These are kids who will grow up as better critical thinkers, with experience reading about science and learning how it applies in "real life." Their own experiences and perceptions won't, as much, form the bases for their realities. Their understanding of what is possible out there, both in science in general, in the universe, and in their own lives, are forever expanded.

Now it's your turn to ride across North America
