STOP M - 1. South Harvard Hill stratigraphy and structure. Walk south to the contact between silicified limestone forming a high ridge and the sands that lie to the southwest of that ridge, then proceed upsection across the ridge, across another ridge and to the dark hill on the northeast. We will discuss the basal thrust fault that places Miocene limestone of the Barstow Formation over Pleistocene deposits of Lake Manix, the stratigraphic sequence above the limestone and its significance, and a higher thrust fault and overlying lake sediments, tuff, and rock-avalanche breccia.
