1874 Asher & Adams Idaho, Montana, Western Portion

This is an original antique map of Idaho and the western portion of Montana, published by Asher & Adams out of New York in 1874.  The work is exceptionally detailed and depicts a surprising number of settlements, villages, towns and small cities in the area of the Rocky Mountains. Idaho is shown with nine counties, and western Montana with eight. Details include railroads, settlements of various sizes, mining districts, Indian reservations and forts. Though known for depicting minimal topography, this map from the Asher & Adams atlas includes most major and some smaller river systems, as well as many mountainous regions.
