On Saturday, November 16, 2013 Mick Meader led a geology walk up Hot Springs Canyon with geology friends Chris Eastoe and James Callegary.  More than 40 people attended.  On this trip, participants learned about the canyon’s geology, its hydrology, and the great variety of rocks in Hot Springs Wash.

The walk began at the end of the drivable road in Hot Springs Canyon about 1/4 mile from the windmill at the Cascabel Conservation Association retreat center.  The walk was about five miles long and took about 6 hours to complete as we stopped and discussed features and rocks along the way.  The walk began with a brief overview of canyon geology, and we then ate lunch in the lower part of Hot Springs Canyon under a grove of sycamore trees.  Afterward we continued upstream to a prominent low-angle fault surface within the canyon. To our surprise, we encountered water in the stream bed a short distance downstream from it.  We hope to follow up with Geology Walk 2, a more strenuous adventure that explores the geology farther up the canyon.
