About this map

Snoqualmie National Forest and Wenatchee National Forest meet at a high-elevation divide in this 2017 survey, where the border between King and Kittitas Counties follows the crest of the Cascade Range. The landscape is defined by massive granite peaks and glacial basins, anchored by Big Snow Mountain and the jagged spires of Chimney Rock.

A dense network of high alpine water bodies drains into the W Fork Foss River and E Fork Foss River, including Big Heart Lake and Angeline Lake. The map details the complex topography of the Necklace Valley, where a string of smaller basins like Jade Lake and Locket Lake are connected by steep terrain. To the south, Overcoat Peak and Summit Chief Mtn mark the rugged transition toward the Kittitas County line, accessible only by primitive forest routes like NFD 5620 RD.
