1979 Map of Mt. Defiance

USGS Topo · Published 1980

About this map

The Columbia River forms a massive corridor through the Cascades on this 1970s survey, marking the boundary between Washington and Oregon. Along the northern shore in Washington, the Little White Salmon National Fish Hatchery and the clustered settlements of Mill A and Mill B reflect the region's managed natural resources and industrial heritage. The landscape is defined by the steep elevation gains from the river level up to the summit of Mt Defiance, where a radio facility and lookout overlook the Columbia Gorge Recreation Area. Transport patterns are preserved here through the dual railroad lines of the Burlington Northern and Union Pacific that hug the riverbanks. High-altitude lakes including North Lake and Warren Lake sit tucked away in the Mount Hood National Forest, while the Pacific Crest Trail traverses the high ridges, connecting the dense network of protected lands such as Viento State Park and Gifford Pinchot National Forest.
