2014 Map of Foundation Ridge

About this map

Snoqualmie National Forest dominates this high-elevation landscape in Yakima County, where the topography is defined by the sharp rise of Foundation Ridge and the prominent Dome Peak. The drainage patterns here are complex, with the headwaters of the N Fork Ahtanum Cr and Middle Fork Ahtanum Cr carving deep routes through McLaine Canyon and Hacket Canyon. The map reveals a series of alpine meadows and flats that provided essential landmarks for forest navigation and resource management, such as Ahtanum Meadows, Dead Horse Flats, and the oddly named Nasty Creek Flats. Small bodies of water like Fish Lake and Long Lake are scattered across the higher reaches, while the transition between Divide Ridge and Strobach Mtn highlights the area's significance for early 21st-century forestry and wilderness access via Nat For Dev Rd 1202.
