Ptarmigan Glacier is located on north slopes of Glacier Peak in the U.S. state of Washington.[2] As is true with all the glaciers found on Glacier Peak, Ptarmigan Glacier is retreating.[3] During the Little Ice Age, Ptarmigan Glacier extended down to an altitude of 4444feet but aside from a small advance during the 1970s, has retreated significantly since the end of the Little Ice Age.[4]
