1969 Map of Thompson Ridge

USGS Topo · Published 1972

About this map

Thompson Ridge dominates this 1960s landscape within the Okanogan National Forest, where a complex network of resource management and wilderness access is visible. The map detail highlights an extensive water-management system along Wolf Creek, featuring a Diversion Dam, a Siphon, and an Aqueduct that contours around the steep slopes. While much of the terrain is defined by drainages like Little Wolf Creek and Bridge Creek, the presence of a Landing Strip near Patterson Lake and numerous segments of Pack Trail and Jeep Trail illustrate the era's reliance on specialized transport for forest monitoring and high-country transit. To the north, the Methow Valley floor begins to broaden, contrasting with the high-elevation landmarks such as Gobblers Knob and the prominent Virginian Ridge.
