Figure 13. Geologic cross section constructed from nearshore seismic profile interpretation (Oldale and O´Hara, 1990; USGS, R. Oldale and R. Rendigs, unpublished data; This Study), a USGS deep borehole (Gerhard and Phillips, 1989), and seismic refraction data (Oldale and Tuttle, 1964). Offshore units, glacial drift (Qd), glaciolacustrine (Qdl), and Paleozoic bedrock (Pz) refer to those mapped by Oldale and O´Hara (1990). The Eastham plain deposit (Qep) is mapped on the surface by Oldale and Barlow (1986). See figure 8, figure 9, and figure 10 for cross-section location.
