This is one of the most desirable editions from this great series of maps covering the Southwest. Arrizona shows up in the southern part of New Mexico Territory. This is thought to represent the Confederate Territory of Arizona that existed for nearly a year from August 1861 until July of 1862. The Confederate General Baylor appointed himself the territorial governor and claimed all of New Mexico Territory south of the 34th parallel. In the southern part of Arizona is the "Gadsden Ten Million Purchase of Mexico." The Utah/Nevada border is too far west on the 116th meridian. Details the Emigrant Road, the Hastings Road, and the routes of numerous explorers and military expeditions. The Gold Region in Colorado's South Park is prominently shown. The map is filled with historic and interesting notations. One note in the area of Quartzite, Arizona refers to the area as being "exceedingly fertile and abundantly timbered and well watered." Additional details include the U.S. Mail routes, the Emigrant road to California, the proposed railroad route through Utah, Nevada and California, and the Pony Express trail, the last time it appears on this series of map. Johnson was diligent in constantly revising his plates with new information. A great map of the Southwest.
