Chetwoot Lake is a freshwater lake located on the western slope of Iron Cap Mountain next to Crawford Lake, in King County, Washington. West Fork Foss River exits Chetwoot Lake towards Angeline Lake and then to a canyon that produces Angeline Falls downstream towards Delta Lake. Because Chetwoot Lake is at the heart of the Alpine Lakes Wilderness, the lake is a popular area for hiking, swimming, and fishing.[2]
Chetwoot is a compound word from the Chinook Jargon chet’-woot or its’woot meaning black bear or grizzly.[3]
Geography
[edit]Chetwoot Lake is nestled in a long structural benchland with relatively level or gently inclined land bounded by the distinctly steeper slopes of Tourmaline Peak on the northwest shore of the lake and Atrium Peak above and between Angeline and Big Heart Lake.[4][5] The lake covers 0.5 kilometres (0.31 miles) from north to south and 1.1 kilometres (0.68 miles) from east to west. The valley follows patterns of geomorphology typical of the Northern Cascade Mountains of the Pacific Mountain System with a bedrock composed of pyrrhotite and pyrite found in thin seams 804 metres (2,638 ft) wide at a depth of 304 metres (997 ft) below the surface.[6] The host rock in this area is greensand from the Lopingian epoch 260 to 250 million years ago.

The warmest month is August, with an average temperature of 13 °C, and the coldest month is January, at an average of −10 °C.[8] The average rainfall is 2,989 millimeters per year.
