About this map

Mt Phelps and Bare Mountain dominate this central Cascades landscape, where the headwaters of several major river systems diverge. The high-altitude terrain is defined by a dense network of glacial basins and alpine waters, including Loch Katrine, Crater Lake, and the Paradise Lakes. This area serves as a critical watershed, feeding the South Fork Tolt Reservoir and the North Fork Snoqualmie River.

Remote forest roads like NFD 5730 RD and specialized routes such as the Bare Mountain Trl provide the only access into the Snoqualmie National Forest and the Alpine Lakes Wilderness. The presence of Prospectors Ridge and the Illinois Basin suggests a history of mineral exploration in these steep reaches, while the numerous creeks—Lennox Creek, Money Creek, and Sunday Creek—carve out the deep drainages that define the local topography.
