This hand-colored map of Washington Territory was issued in the GLO's annual report for 1866. It shows good detail in the coastal regions with additional completed surveying extending east along the Columbia River. Steven's proposed railroad route is shown and a legend at bottom identifies land offices, wagon roads, and minerals including silver, gold, lead and coal. Settlement is very sparse with only a few towns noted including Seattle, Vancouver, Walla Walla, and Olympia.
