In the Philip Smith Mts, Ribbon River valley, 27 mi NE of Galbraith Lake, drains E to Ribdon River 15 mi. SE of its junction with Sagavanirktok River, Brooks Range. 2 miles long.
So named by U.S. Geological Survey (USGS) geologists in 1951 because it "is elusive to ground traveller because (the lake is) hidden behind low hills on its NE side."
