Hinman Glacier lies to the north and northwest of Mount Hinman, in the U.S. state of Washington. Hinman Glacier is within the Alpine Lakes Wilderness of Snoqualmie National Forest. The glacier is approximately .35 mi (0.56 km) in length and descends from 7,400 to 6,400 ft (2,300 to 2,000 m), where it terminates on barren rock. The western lobe of Hinman Glacier consists of small patches of ice and has essentially disappeared. The glacier persists only on the north flank of Mount Hinman. Repeat photography indicates that Hinman Glacier has retreated significantly.
