PATAGONIA, ARIZONA
Below: LAAW and Borderlands Restoration group at the wildlife corridor; Rock dams are built in areas where erosion washes away earth and vegetation. The damns catch silt and become populated with vegetation. The Institute uses rocks, branches and sometimes donated post consumer construction materials from demolition to build the dams. This has been the year of concrete, brick, rock and building for FAM.

GILA WILDERNESS
In the Gila the rock is sunset colours. You can find openings to former florite mines and purple, green and golden florite and quartz crystals can be found on the ground. As a semiarid desert (less than 20 inches of rain per year), the Gila has a river and hot springs. Many hot springs are maintained by volunteers in a DIY fashion. The one below was made with two basins fashioned with rock, lined with tarp and fed by a pipe.
