Very attractive and finely engraved map showing Lt. G.K. Warren's routes in 1855 and 1856. Warren's tracks are highlighted in red as they traverse the Northern Plains between the Missouri River and the Rockies. The map extends to the Wasatch Mountains and the Green River in the southwest and the Chippeway Indian land and Rainy Lake in the northeast. It locates numerous forts and Indian lands. Watershed and topographical details include the elevations of river basins, plains and countless mountain peaks.
Fine original outline color, full margins and bright impression. One faint foxing area at lower left corner, else fine.
