Surprise Mountain is a 6,330-foot (1,929-metre) mountain summit located above the southern end of Glacier Lake, in eastern King County of Washington state.^[6] It is part of the Wenatchee Mountains, which are a subset of the Cascade Range, and is situated in the Alpine Lakes Wilderness, on land managed by Mount Baker-Snoqualmie National Forest.^[1] Precipitation runoff from the mountain drains into Surprise Creek and Deception Creek, both tributaries of the Skykomish River. The nearest higher neighbor is Thunder Mountain, 0.88 mi (1.42 km) to the northeast, and Terrace Mountain is set three miles (4.8 km) to the southwest.^[1] The Pacific Crest Trail skirts this peak as it passes through Surprise Gap.
