A remarkable and attractive map with a detailed representation of the various routes of western expeditions and the historic surveys of King, Wheeler, Powell & Hayden. Among the details are the locations of occupied and abandoned posts, signal service stations, telegraphic lines, routes of cattle droves and trains, and more information on explorer's routes than we've seen on any map. The map reflects the survey efforts during the seasons of 1869 to 1879.
