About this map

Snoqualmie National Forest dominates this high-elevation landscape in Yakima County, where dramatic topographical features define the drainage patterns of the eastern Cascades. The survey captures a complex network of ridges and meadows, notably the prominent Foundation Ridge and the broad Ahtanum Meadows to the south. Waterways like N Fork Ahtanum Cr and the various branches of Foundation Cr carve through the terrain, separated by distinctive landmarks such as Whites Ridge and Ewe Neck.

Remote access is traced through primitive routes including 4wd Hog Back and 4wd Divide Ridge, reflecting the area's use for forest management and recreation. High points like Strobach Mtn and Dome Peak stand above a series of named flats and meadows, including Dead Horse Flats and Nasty Creek Flats, providing a detailed look at the geographical naming conventions used by early surveyors and foresters in this section of Washington.
