(Oregon - Idaho) Map Showing the Route Traveled by the Command of Maj. E. Steen, U.S. Drags., Against the Snake Indians in 1860, by Lieut. Joseph Dixon U.S. Topl. Engrs from explorations and surveys made by him while attached to this Command...
At the time Steen followed the Indians into eastern Oregon the region was substantially unexplored, but this map does much to remedy that fact. It shows the routes of the troops through this country between the Cascades and the Snake River. Although it is a step ahead in understanding the region, there are areas that are treated honestly and labeled "Unexplored".
Condition is good, with repairs, light browning to the folds and some minor loss at fold junctions. Image size is approximately 24.25 x 34 (inches)
