About this map

Snoqualmie National Forest and Wenatchee National Forest meet along a dramatic divide defined by the King Co Kittitas Co boundary. The landscape is dominated by a complex network of alpine water bodies, including the expansive Lake Dorothy and the clustered Tank Lakes. The topography reveals the intricate drainage patterns of the Cascade Range, with numerous named peaks such as Big Snow Mtn and Summit Chief Mtn serving as anchors for the surrounding wilderness.

A network of pack trails, including the (Pack) Trail through the Necklace Valley, provides a record of human access into this high-elevation environment before modern infrastructure. These routes connect isolated features like Chetwood Lake and Otter Lake, tracing the paths used by early surveyors and foresters. The inclusion of the Usmm 2 landmark underscores the importance of this terrain for geodetic surveying in the mid-20th century.
