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.[2] The glacier descends from the White Salmon Glacier at 10200feet to a terminus near 7600feet. 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.[3]
