Columbia River Valley -- Maps

1 map : 33 x 33 cm.<br>"Sen. Ex. Doc. No. 186, 1st sess., 47th Cong."<br>Scale approximately 18 miles to 1 inch. <br>In September and October of 1881, under orders from Brig. Gen. Nelson A. Miles, Thomas W. Symons traveled and closely mapped the entirety of the Columbia River from the Canadian border to the point where the Snake and Columbia Rivers met. His stated goal was "to determine its navigability and the advisability of putting steamboats on it to be used in the transportation of troops, stores, supplies, &c." This map consisted of this index page, the 25 more detailed maps indicated on the index, and a few smaller close-up maps of the more obstructed parts of the river. Symon's report also included historical and geological notes on the Columbia and its basin, as well as notes on improving the navigability of the River.
