About this map

The boundary between King County and Kittitas County bisects this mountainous landscape where the Cascades' drainage systems diverge. The northern portion is dominated by the Snoqualmie Pass area and the western reaches of Keechelus Lake, while the Pacific Crest National Scenic Trail winds along the high ridges, passing Silver Peak and Mt Catherine. The terrain is defined by its numerous alpine water bodies, including Annette Lake, Mirror Lake, and the namesake Lost Lake.

South of Yakima Pass, the hydrology shifts toward the Cedar River watershed, with the North Fork and South Fork Cedar River drawing from the slopes of Meadow Mountain. This region, split between the Wenatchee National Forest and Snoqualmie National Forest, contains a dense network of Forest Service development roads like National Forest Development Road 5000 S, which facilitate access to the high passes and notches.
