I didn't know about this striking rock formation in the Tonto National Forest, AZ.  It is referred to as China Wall, "a broken vertical wall nearly a mile long (1.6 km), and about 10 feet high (3 m) and 5 feet wide (1.5 m)."

Earth Science Picture of the Day  (EPOD) includes 4 striking photograph plus a satellite photograph. And an explanation of the geology on its origin. It consists of rhyolite rock.
