Is the Nisqually Glacier retreating?
It is currently retreating. Measurements made at 9,200 feet (2,800 m) altitude show that glacier got 56 ft (17 m) thicker between 1994 and 1997, suggesting that it will probably begin advancing in the first decade of the 21st century. Nisqually Glacier is the source of the Nisqually River.
