Topographic map of the San Pedro Hills: Supplement 1 from "Report on the Geology of the San Pedro Hills" (Thesis)

Description

The San Pedro Hills Area is composed of Basement Complex overlain by a series of late Tertiary and Quaternary marine sediments. There is a series of intrusive rocks forming sills and laccolithic masses in the vicinity of San Pedro Hill. There is a great abundance of fossil material in the very late Tertiary and Quaternary beds, offering ample opportunity for the paleontologist to accurately zone the different formations. The folding is quite acute, but there has been no important faulting in the area.
