Flett Glacier is actually two glaciers on the northwestern flank of Mount Rainier in the U.S. state of Washington. The glaciers actually lie on a subsidiary peak of Rainier, the 8,364 feet (2,549 m) Observation Rock. There are two sections of glacial ice, an eastern lobe at about 7,600 ft (2,300 m) to 7,300 ft (2,200 m) in elevation, a smaller western lobe at about 7,200 ft (2,200 m) in elevation. Meltwater from the glacier flows into the Puyallup River.
