About this map

Ernies Grove sits at the edge of a high-elevation wilderness dominated by the dramatic peaks of the Cascade Range. This landscape is defined by massive topographical features like Mt Si and Mt Teneriffe in the south, which overlook a complex network of glacial lakes and mountain streams. The North Fork Snoqualmie River carves through the western portion of the map, fed by numerous tributaries such as Calligan Cr and Hancock Cr.

Deep within the Snoqualmie National Forest, dozens of high-country water bodies including Calligan Lake, Lake Hancock, and the smaller Lake Moolock are connected by a web of Forest Service access roads. The presence of Metcalf Marsh and Crater Lake suggests a diverse alpine environment where water management and forestry remain central to the local geography. Notable landmarks like Fuller Mtn and Green Mtn provide distinct navigational points for those studying the natural history and land use patterns of King County.
