This large folding map, published in 1860, details the surveys conducted to locate a northern route (47th and 49th Parallels) on an expedition led by Isaac Stevens, Governor of Washington Territory. Most of the map covers Montana, with extraordinary detail and excellent relief, naming rivers, numerous routes with dates, and interesting topographical commentary.

Good impression. Folding as issued, with a little toning along some folds and two intersection splits, else very good.
