Unicorn Peak is a 5,100-foot summit in Washington’s Olympic Mountains, within Olympic National Park’s Daniel J. Evans Wilderness, rising sharply above the Elwha valley west of Port Angeles. Also called Unicorn Peaks and The Pinchers, it forms a paired shape with nearby Unicorn Horn. In Klallam tradition, these peaks figure in a great flood story in which canoes were tied to the mountaintop before the summit broke apart and the survivors drifted to the place where Seattle now stands. The peak lies in a wet marine climate with heavy rain, dense winter snow, and avalanche danger, and its rugged form was shaped by oceanic rock, erosion, and repeated Pleistocene glaciation.
