About this map

Snoqualmie National Forest dominates this high-elevation landscape in Yakima County, where dramatic elevation changes are defined by Foundation Ridge and Whites Ridge. Surveyed in the late 1960s, the area is a complex network of seasonal meadows and water sources, including Pickle Prairie Meadows and Sleepy Park Meadow. The presence of the Ahtanum Guard Sta and the Ahtanum Meadows Campground near Ahtanum Creek suggests the area's ongoing importance for forest management and backcountry recreation.

A network of Pack Trails and Jeep Trails provides the primary access to notable landmarks like Strobach Mtn and Dome Peak. The drainage patterns are clearly delineated, showing how Nasty Creek and the forks of Foundation Creek cut through the terrain. Evidence of localized industry appears at a Gravel Pit located along the creek, reflecting the material needs of maintaining these remote forest routes.
