2023 Map of Mount Si

USGS Topo · Published 2023

About this map

Ernies Grove and the surrounding high-altitude lake country define this corner of the Cascade foothills. The terrain is characterized by a dense network of water bodies and dramatic elevation changes, notably the iconic peaks of Mt Si and Mt-Teneriffe in the southern reaches. The North Fork Snoqualmie River carves through the central valley, flanked by timber access roads like N Fork Rd SE and Tolt Reservoir Rd. The map reveals a landscape managed for both preservation and utility, with the eastern half largely dedicated to the Snoqualmie National Forest and the Alpine Lakes Wilderness. Numerous smaller basins, including Lake Hancock and Calligan Lake, dot the plateaus, while lower-lying features like Metcalf Marsh near Fuller Mtn illustrate the complex drainage patterns of the Snoqualmie watershed before it descends toward the lowlands.
