Mazama Glacier

Mazama Glacier lies on the southeast slopes of Mount Adams in Washington within the Yakama Indian Reservation, descending along the stratovolcano’s flank from about 10,800 feet to a terminus near 7,600 feet. Originally called Hell-roaring Glacier, it received its present name in 1895 from a party of the Mazamas mountaineering club during its second annual outing. Along its eastern edge on Suksdorf Ridge, the Lunch Counter camp sits at about 9,350 feet. The glacier has generally retreated for more than a century, losing 46 percent of its surface area between 1904 and 2006 as part of Mount Adams’s long-term ice shrinkage.
