McCartney Peak is a 6,784-foot-elevation (2,068-meter) mountain summit located within Olympic National Park in Jefferson County of Washington state.
Part of the Olympic Mountains, McCartney Peak is situated 18 miles south of Port Angeles, and set within the Daniel J. Evans Wilderness.
Topographic relief is significant as the southwest aspect rises 3,800 feet (1,200 meters) above the Lost River in approximately 1.5 mile.
As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow.
[8] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
