This open-file report describes the carbon-sequestration potential at the site of the 1 Alpine-Federal geothermal test drill hole, which is located south of Springerville in central eastern Arizona near the New Mexico border. A previous report, Arizona Geological Survey (AZGS) Open-File Report OFR 94-1, version 2.0, describes the subsurface geology encountered in the 1 Alpine-Federal well in much more detail than this new report.

This field trip guide was created for a Project WET conference held in Tucson, Arizona, June, 2007. This guide discusses the general geology of the Santa Catalina Mountains in Sabino Canyon, and points out evidence of the July 2006 floods and debris flows. There are stops in the first few miles of canyon, and towards the end of the tram road, where the most spectacular debris flows are located.
