Gotchen Glacier is located on the south slopes of Mount Adams a stratovolcano in the Gifford Pinchot National Forest in the U.S. state of Washington. The glacier descends from approximately 8200 ft (2500 m) to a terminus near 7400 ft (2300 m) below which an old terminal moraine and proglacial lake exist. Gotchen Glacier has been in a general state of retreat for over 100 years and lost 78 percent of its surface area between 1904 and 2006.
