For the next couple of winters, any storms with a lot of rain are going to make the San Gabriel range flow into debris basins and Pasadena.
After the Oakland Hills fire, officials sprayed the steepest hillsides with goo to glue the dirt together, mixed with wildflowers seeds - and the next few springs were stupendous. I'm not sure there's enough glue in the world for the San Gabriels, one of the fastest-rising and most fragile mountain ranges in the world -- but I hope they try something like that.
Thanks to Ian O'Neill for the pointer.
