Suiattle Glacier is located in the Glacier Peak Wilderness in the U.S. state of Washington. The glacier is within Mount Baker-Snoqualmie National Forest and nearly touches Honeycomb and White River glaciers separated from them by an arête off the Kololo Peaks at its uppermost reaches.[2] Suiattle Glacier has retreated significantly since the end of the Little Ice Age, and from approximately the years 1850 to 1924 lost 1,400 m (4,600 ft) of its length. Between 1924 and 1940, the glacier retreated an additional 900 m (3,000 ft), then during a cooler and wetter period between 1967 and 1979, the glacier had a small advance of 20 m (66 ft).[3] After this, Suiattle Glacier began to retreat again and has retreated 270 m (886 ft) from its advanced position in the 1970s to 2009.[4]
