1980 Map of Keystone

USGS Topo · Published 1981

About this map

Okanogan River corridor life in the late 1970s is defined by the narrow ribbon of industry and transport pressed against the water, including the Burlington Northern railroad and the Keystone Road. The small settlement of Keystone sits just south of the McAllister Rapids, serving as a waypoint in a landscape dominated by the complex terrain of the Tunk Valley.
