This guidebook includes the San Diego Association Geologists’ 2005 and 2006 field trips. We begin our exploration in the Peninsular Ranges Batholith in southern San Diego County along historic Old Highway 80 and the San Diego & Arizona Eastern Railway. The trip continues east over the Laguna Mountain Escarpment into the breakaway zone of the Salton Trough, mainly off road along rough jeep tracks and hiking trails.
