Basic map stuff - How colors are used

Years ago, in physical geography, we had to color in a physiographic map of the United States. I loved that activity, with colored pencils, and thin pens, and geology references. The teacher told us that we could choose our own colors, and one student showed him her map with the sea colored orange. He said, "I know I told you that you can choose your own colors . . . but just no. No. The sea cannot be orange." And he had her start over. It was sad, but . . . just no.

I titled a previous post "that's right it starts with an earthquake, birds, snakes, and aeroplanes," and it's tacky to do that again, and so I won't.

Instead, I'll just give you this, a whole set of Redoubt photos, most showing the eruption, and a few, like this, with dramatic lightning.

I wouldn't mind watching this, with protection from the ash, and some distance.

Wow.

I did not take this photo, it comes from the Alaska Volcano Observatory.
