U.S. DEPARTMENT OF THE INTERIORU.S. GEOLOGICAL SURVEY

Base compiled from aerial photographs taken 1987Field checked 1988. Map edited 1991Lambert Conformal Conic projection. 1927 North American datum10,000-foot grid based on California coordinate system,zone 51,000-meter Universal Transverse Mercator grid ticks,zone 11

Geology was mapped 1997-1998. Digital assistance byAmy L. Zoller and D. Paco VanSistine. This map is preliminary and has not beenreviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic code.

This map was produced on request, directly from digital files, on an electronic plotter.It is also available as a PDF file at http://pubs.usgs.gov/of/2002/ofr-02-402
