Avalanche Glacier is located on the west to southwest slopes of Mount Adams a stratovolcano in the Gifford Pinchot National Forest in the U.S. state of Washington.[3] The glacier descends from the White Salmon Glacier at 10,200 ft (3,100 m) to a terminus near 7,600 ft (2,300 m). Avalanche Glacier has been in a general state of retreat for over 100 years and lost 59 percent of its surface area between 1904 and 2006.[2]
