2014 Map of Mount Si

About this map

Ernies Grove sits at the edge of a dense network of mountain peaks and alpine lakes within the Snoqualmie National Forest. The geography is defined by the steep elevation gains toward summits like Mt Si and Mt Teneriffe, which overlook the winding course of the North Fork Snoqualmie River. This area serves as a significant drainage basin for numerous high-altitude water bodies, including Lake Hancock, Calligan Lake, and Lake Philippa, each feeding into creeks that cut through the steep topography. An extensive network of forest roads, such as Tolt Reservoir Rd and SE N Lake Hancock Rd, provides the primary access into these timberlands. The map reveals the relationship between the valley settlement and the protected wilderness, showcasing how water systems like Hancock Cr and Calligan Cr descend from the upland lakes toward the river valley below.
