2005 ANNUAL FIELD TRIP

The geology and lore along the highways and byways of southeastern San Diego County was the focus of our 2005 field trip. The route loosely followed old U.S. Highway 80, and the San Diego and Arizona Eastern Railway, examining a variety of subjects of historical, mineralogical, petrological, hydrological, archaeological, not to mention downright trival, interest. SDAG members "camped" in Jacumba, at the Jacumba Hot Springs. Field trip stops included: the Cuyamca/Laguna Mountain Shear Zone, the western margin of the La Posta Pluton, the Pacific Southwest Railway Museum, the Motor Transport Museum, the historic Desert View Tower, and several sites "down the hill" in the Dos Cabezas area.
