About this map

Pacific Crest National Scenic Trail traverses the high ridges of the Cascades here, crossing the boundary between the Snoqualmie National Forest and Wenatchee National Forest. This 1989 survey details a complex hydrological landscape where the City of Seattle and City of Tacoma maintain critical water interests through the Cedar River Watershed and Green River Watershed. High mountain passes like Yakima Pass and Meadow Pass serve as natural transition points across the King and Kittitas County line.

The topography is punctuated by prominent summits including Silver Peak, Mount Catherine, and Tinkham Peak. Alpine lakes are scattered throughout the terrain, from the large Keechelus Lake in the northeast corner to the smaller Annette Lake, Mirror Lake, and the namesake Lost Lake. A Fort Tilton Historical Marker near the North Fork of the Cedar River provides a specific point of historical interest in an otherwise largely unpopulated wilderness area.
