Cactus and city at Corbett School

As you drive along Sonoita Avenue, north from 29th, you'll see this mural on your left, on the east wall of Corbett School, at the corner of 28th Street. (Remember that you can click on the photo for a larger view.)

Update (September 26, 2012): Here are three close-ups of parts of the mural, from the north end to the south, that I snapped today:

The bright parts of the second close-up are spots of morning sunlight.
