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.[3] The glacier descends from approximately 10,800 ft (3,300 m) to a terminus near 7,600 ft (2,300 m).[3] 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.[2]
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.[4]
Lunch Counter camp lies along the eastern edge of Mazama Glacier, upon Suksdorf Ridge at an elevation of 9,350 ft (2,850 m).[5] There is no weather station, but this climate table contains interpolated data.
