Lyman 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 is also within the Yakama Indian Reservation and descends from near the summit of Mount Adams at approximately 11400 ft (3500 m) to a terminus near 7800 ft (2400 m). Below 9000 ft (2700 m) the glacier splits into three distinct lobes.
