Sunset Falls, on Washington’s South Fork Skykomish River, is the last of the river’s three main falls and drops 104 feet through a long, narrow chute nearly 300 feet long, creating an unusually forceful, compressed torrent. The river is thought to reach about 37 miles an hour there, and during high water, potholes in the rock can blast water outward up to 30 feet. The falls also hold a notable place in whitewater history: on May 30, 1926, Al Faussett successfully ran them in a canoe before hundreds of spectators. Later kayak descents highlighted the danger of this class 6 rapid, which has unavoidable, potentially deadly hazards.
