A terrific, richly colored map of the Pacific Northwest that shows Washington Territory in its most unusual configuration, wrapping around the new state of Oregon. Of specific interest is the notation of the major exploration routes, wagon trails and the proposed routes for the transcontinental railways. This map was published by Johnson & Browning shortly after Oregon became a state in 1859. The organized counties of both Oregon and Washington are confined west of the mountain ranges except for Skamania and Walla Walla Counties. The map is surrounded by Colton's signature strapwork border. A very lovely example.

A beautiful example with strong impression, full margins and bright original hand coloring. A very thin line of damp staining along edge, well away from map.
