Caldera boundaries modified after Williams and others (1997), Loucks and others (1989), Raines and others (1996), Workman and others (2002), and Gans and others (1989). Boundaries of highly extended terrains modified after Wernicke. Base from U.S. Geological Survey digital data 1:100,000, 1978-1989; Universal Transverse Mercator projection, Zone 11. Shaded relief base from 1:250,000-scale Digital Elevation Model; sun illumination from northwest at 30 degrees above horizon. ’ B-B EXPLANATION EUREKA CO. SW SECTION NE WHITE PINE CO.
