Figure 3. Two possible geologic profiles along Lehman Creek showing (A) granite intrusion splitting Pole Canyon Limestone and (B) granite replacement of Pioche Shale between Prospect Mountain Quartzite and Pole Canyon Limestone beneath alluvial and glacial deposits at Cave Springs, Great Basin National Park, Nevada. Cross section A modified from Elliott and others, 2006 (fig. 18). Geologic profiles were drawn on the basis of geology by Hose and Blake (1976) and Miller and others (1995a and 1995b). Location of profile is shown in figure 2.
