A majority of this map covering the entire state of California is hand colored to reflect geological knowledge and coded in accordance with a legend at the left. The legend identifies nine geological types as mapped by Lieut. R.S. Williamson of the Topographical Engineers. There are interesting details throughout, and especially along the American River. Shows a huge Mono Lake, but Lake Tahoe is not shown; rather in its place is a small lake named Lake Bonpland. In Southern California, Los Angeles, San Gabriel, San Pedro, and more are located. Interestingly, the water between San Pedro (Long Beach) and San Diego is called "Earthquake Bay." Prepared to accompany the report of William P. Blake, Geologist of the Expedition. Lithographed by Sarony, Major & Knapp of New York.
