This superb, large map is from the first edition of the General Land Office annual report. Issued at the end of the Civil War, these maps were designed to provide a visual depiction of the progress of public surveys, settlement and commercial development, and, most importantly, the mineral resources throughout the West. The map depicts a wealth of information including gold, silver, and copper mines, along with wagon roads, forts, early settlements, private land claims, and Indian land grants. Arizona has only five counties including the short-lived Pah-Ute County in the extreme northwest corner. New Mexico has 13 forts and only nine counties with most development confined to the river valleys. Also noted are the exploration routes of Ives and Whipple, the Old Spanish Trail, and the Former Overland Mail Route to California. The map provides a fascinating record of the opening up of the Southwest and is one of the best, and scarcest, early government maps of Arizona and New Mexico.
