2017 Map of Devils Slide

About this map

Snoqualmie National Forest dominates this mountain landscape in King County, where the hydrological network of the Tolt and Snoqualmie rivers defines the terrain. The central geography is anchored by the S Fork Tolt Reservoir, a significant water resource fed by the S Fork Tolt River. The namesake Devils Slide sits to the north, overlooking a high-elevation environment dotted with alpine features like Lake Titicaca and Lunch Lake. This 2017 survey details the complex system of forest roads, such as Nat For Dev Rd 6200-4 and Tolt Reservoir Rd, which provide access through the timberlands. The southern portion of the quadrangle shifts toward the North Fork Snoqualmie River watershed, including the drainage of Sunday Cr and the marshy margins of Fitchener Slough.
