Gneiss walk

Interested in learning about the geology of Sabino Canyon? Of course you are. Because rocks rock! Join Bruce 'Garnet' Garrett and the Catalina Gneiss Rockettes for a Gneiss Walk, every Thursday from 11/10/11 until the end of April. Meet at the visitor center at 8.30am; plan for 3 hours on moderately difficult trails. (The mysteries of the photo above will be revealed...)
