Rare map showing Northwest Oregon and the lands and routes traveled during the first expeditions of the area, especially the region between the Cascade Mountains east to the Snake River. Great details in topography and mountain range identification, as well as documenting specific battles and routes, both by explorers and native peoples. Cool map with great regional content.

 Major Enoch Steen, commander of the U.S. Dragoons, was sent to the area in 1860 to determine the feasibility of routes from the Willamette Valley to southeastern Oregon. However, Steen's historical fame rests on his pursuit, during the expedition, of Paiute (Snake) Indians up the Donner and Blitzen River and into the rough Wildhorse Canyon. According to Wheat, “this was a decisive campaign; the Snakes were defeated and their movements rigorously curtailed.”

Steen’s report to the Senate of his explorations in Oregon contained the present map by Joseph Dixon. The map depicts the area from Fort Boise on the Snake River west to Fort Vancouver on the Columbia River. It details the routes of Steen and several scouts against the Snake Indians, as well as showing the Oregon Trail (“Emigrant Road”), the proposed route to “Eugene City,” Indian trails, camps, battlegrounds, forts, astronomical stations, topography, and rivers, and it notes several large unexplored regions of the Blue Mountains. 

An excellent mid-nineteenth-century map of Oregon, called “extensive and well-made” by Wheat.

Published by J. Bien & Co. in "Topographical memoir of the command against the Snake Indians, under Major E. Steen, United States Dragoons, in the summer of 1860."
