About this map

The Middle Fork Snoqualmie River carves through the heart of the Alpine Lakes Wilderness and Snoqualmie National Forest in this 2023 survey. This high-elevation landscape is defined by its glacial hydrology, where Lake Philippa and the Twin Peaks overlook a network of alpine basins containing Mowitch Lake, Rainy Lake, and Lake Blethen. The topography is exceptionally steep, rising to summits like Bessemer Mtn and Garfield Mtn, which frame the deep drainage of the Taylor River.

Forest access and recreation are traced through primitive routes such as the Middle Fork Trl and C C C Trl, alongside remnants of old timber and management corridors like Sunday Creek Rd. The presence of Devils Canyon and named tributaries like Lennox Creek and Calligan Creek highlights the complex watershed that feeds the Snoqualmie system. This modern map preserves the nomenclature of the peaks and lakes that have drawn explorers and land managers to these peaks for generations.
