Lava Glacier is located on the north slopes of Mount Adams a stratovolcano in Gifford Pinchot National Forest in the U.S. state of Washington. The glacier descends from approximately 10000 ft (3000 m) to a terminus near 7800 ft (2400 m). Lava Glacier has been in a general state of retreat for over 100 years and lost 74 percent of its surface area between 1904 and 2006.
