Mazama Glacier (Mount Adams)

Mazama Glacier is located on the southeast slopes of Mount Adams, a stratovolcano in the U.S. state of Washington. Mazama Glacier is in the Yakama Indian Reservation. The glacier descends from approximately 10,800 ft (3, 300 m) to a terminus near 7,600 ft (2, 300 m). Mazama Glacier has been in a general state of retreat for over 100 years and lost 46 percent of its surface area between 1904 and 2006. Originally known as Hell-roaring Glacier, the name was changed in 1895 by a group from the Mazamas club while they were on their second annual outing.
