1963 Map of Peterson Ridge

USGS Topo · Published 1973

About this map

Peterson Ridge and the high country of the Blue Mountains dominate this 1960s survey along the boundary between Washington and Oregon. This area, divided between Walla Walla and Umatilla Counties, is defined by its dramatic drainage systems, including the headwaters of the North Fork Walla Walla River and the deeply cut Little Meadow Canyon. The landscape is etched with steep ridges like Pine Ridge and Blalock Mountain, reflecting a remote terrain where transit was limited to early roads and a Jeep Trail.
