2014 Map of Big Snow Mountain

About this map

Big Snow Mtn dominates the western half of this alpine landscape, where high-elevation drainage systems feed the Middle Fork Snoqualmie River and the W Fork Foss River. The terrain is characterized by massive rock formations such as Chimney Rock and Overcoat Peak, bordering the boundary between the Snoqualmie National Forest and Wenatchee National Forest. This 2014 survey reveals a dense concentration of glacial basins, including the Necklace Valley Lakes and large bodies of water like Big Heart Lake and Angeline Lake. The sheer verticality of the region is evidenced by features like Malachite Falls, which drops from the peaks near Malachite Lake. This map serves as a primary source for the complex hydrography and glaciated topography that define the high Cascades on the border of King and Kittitas counties.
