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.

A Radio Tower atop Pikes Peak stands as one of the few structural landmarks in this high-elevation region. The water-rich geography is evidenced by numerous named flows such as Cottonwood Creek, Mormon Creek, and Birch Creek, which descend from summits like Saddle Mountain and Government Mountain. This map provides a clear record of the watershed and topographic layout of the border country before modern developments altered the access to these slopes.
