Stonesthrow Lake

Stonesthrow Lake is a small freshwater lake located within the Alpine Lakes Wilderness in a valley on the eastern slope of Rampart Ridge in Kittitas County, Washington, United States. Because of its close proximity to Snoqualmie Pass, Interstate 90 and several cirque on both sides of Rampart Ridge, the lake is a common area for hiking, swimming, and fishing cutthroat trout and rainbow trout. Keechelus Ridge is a short distance south on trail 4934 which covers the length of the ridge. Stonesthrow Lake is between Keechelus Lake on the West and Kachess Lake further East.

Location
Stonesthrow Lake sits on the eastern aspect of the meadow valley it shares with Margaret Lake on the eastern skirt of Mount Margaret. Swan Lake and Rock Rabbit Lakes are a short distance southeast, on the north aspect of Keechelus ridge.
