Nooksack Falls is a waterfall along the North Fork of the Nooksack River in Whatcom County, Washington. The water flows through a narrow valley and drops freely 88 feet into a deep rocky river canyon. The falls are viewable from the forested cover near the cliffs edge. The falls are a short 2/3 of a mile drive off the Mount Baker Highway, Washington (State Route 542). The falls were featured in the hunting scene of the movie The Deer Hunter.
