Very nice geological survey map from the Pacific Ocean (at San Francisco included) through the San Joaquin Valley to the Sierra Nevadas, CA, as explored by R Williamson and issued by the War Department.  This is part of the very large effort to survey the land in conjunction with the construction of the Pacific Rail Road.  Colored.
