San Diego Aerial

Here's a picture of San Diego from the airplane window. The large green block in the center is Balboa Park and the San Diego Zoo. As opposed to LA, you can tell that San Diego is anything BUT flat. In fact, you can see the green tendrils of the finger canyons all over the city which, by the way, was build on a large natural plateau which has eroded into valleys and canyons. I also suspect that the sandy, rocky soil resulted from ocean sediment that has been forced upwards as the Pacific Plate slowly moves up the continental plate.
