About this map

Mount Phelps and the high ridges of the Cascades define this pocket of King County, where a legacy of hard-rock prospecting is preserved in the names of numerous extraction sites. Scattered throughout the drainage basins of the North Fork Tolt River and North Fork Snoqualmie River, mines such as the Damon Mine, Apex Mine, and Blackhawk Mine indicate the area's industrial importance to the region's mineral history.

Water management and conservation are central to the landscape, dominated by the South Fork Tolt Reservoir and the protected South Fork Tolt Watershed. Remote high-altitude lakes, including Loch Katrine, Sunday Lake, and the Paradise Lakes, are connected by a network of Forest Service roads like NFD 5700 Rd. On the eastern edge of the quadrangle, the Bare Mountain Lookout stands as a sentinel over the Illinois Basin, marking a point of observation for this heavily forested and high-elevation terrain.
