Mineralogy and Geology of Mina El Fenómeno,
Sierra Juarez, Baja California

September 21 - 22, 2002

The 2002 San Diego Association of Geologists (SDAG) annual field trip and associated volume is "Geology and Mineral Resources of Northern Baja California. Mexico". The trip looks at the La Posta-type intrusives in the Sierra Juarez; a visit to the abandoned scheelite mine, El Fenómeno; coastal faulting, geology, and associated marine terraces. The Field Trip chair and editor of the guidebook is Patrick Brooks.

Saturday morning 6:30AM - starting location: Rancho San Diego shopping center parking lot at the corner of Jamacha Road and Highway 94. Stop 1 - La Posta-type intrusives; Stop 2 The El Fenómeno Mine; Stop 3 Other nearby mines; Stop 4 Campground at East Kennedy Cove - Punta Banda. Saturday night - camp and catered dinner. Beverages provided by SDAG.

Sunday - simple continental breakfast and campground departure, followed by Stop 1 Agua Blanca Fault; Stop 2 Rincón de la Ballena [at Punta Banda]; Stop 3 UABC campus; Stop 4 Los Hornos [old road to Tijuana].

TRANSPORTATION: Once we leave Highway 3 east of Tecate, a high clearance vehicle is required, since the road is dirt most of the way to Ojos Negros. The road to the campground is rough also. Four-wheel drive is not necessary.
