1967 Map of Foundation Ridge

USGS Topo · Published 1970

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.
