Elk Mountain is a 6,773-foot summit in Washington’s Olympic Mountains, within Olympic National Park at the eastern end of Hurricane Ridge. It stands between two drainage systems, with its south slope feeding tributaries of the Dungeness River and its north slope draining through Morse Creek to the Strait of Juan de Fuca. Shaped by a marine west coast climate, it is known for heavy winter rain and snow, wet dense snowpacks, and avalanche danger, while clearer summer weather can prevail. Its rocks include obducted clastic wedge material and oceanic crust, and repeated Pleistocene glaciation and erosion helped form its present landscape.
