"Geological Map of the Route explored by Lt. A.W. Whipple…From the Mississippi River to the Pacific Ocean 1853-1854", Whipple, Amiel Weekes

A very colorful map that details the country from Memphis across the west to the small town of Los Angeles. The underlying geology surveyed by the notable geologist, Jules Marcou, is delineated and color-coded with an index. The Atchison, Topeka and Santa Fe Railroad later traveled the western part of this survey. Locates a few cities along the way: Helena, Napoleon, Vicksburg, Pine Bluff, Little Rock, Fort Smith, San Antonio, Fort Defiance and Needles.
