This is the later 1864 edition and is one of the first maps to show the original four counties of Yavapai, Mohave, Yuma and Pima in the newly organized Arizona Territory. The Utah/Nevada border is now at 114° and Arizona has its final borders. Details the U.S. Mail routes, the Emigrant roads to California, the proposed railroad route through Utah, Nevada and California, and the Pony Express trail. Terrific details throughout.
