Bold and attractive map has a detailed representation of the various routes of western expeditions and the historic surveys of King, Wheeler, Powell and Hayden. This edition includes the survey seasons of 1869 and 1871 through 1877. Among the details are the locations of occupied and abandoned posts, signal service stations, telegraphic lines, routes of cattle drives and trains, and more information on explorers' routes than we've seen on any map. A remarkable and historical document of the surveys in the west.
Issued folding, now backed with archival tissue. Some very faint toning along folds and edges, otherwise near fine.
