Hinman Glacier
Hinman Glacier was a glacier that flowed to the north and northwest from near the summit of Mount Hinman, in the U.S. state of Washington. Hinman Glacier was within the Alpine Lakes Wilderness of Snoqualmie National Forest. The glacier was approximately 1.3 km² in 1971, making it the largest glacier between Mount Rainier and Glacier Peak, but an expedition by glaciologists from Nichols College in August 2022 discovered that the glacier had disappeared, with only a few snowfields and non-flowing remnant ice areas totalling 0.04 km² remaining. Smaller glaciers in this part of the Cascade Range preceded the Hinman Glacier in disappearing as part of the retreat of glaciers since 1850 with only three glaciers remaining in King County. Made up of two sections, the western lobe was the first to disappear, leaving only small patches of ice by 2009. The glacier persisted on the north flank of Mount Hinman for another decade and repeat photography showed rapid retreat.
