Flett Glacier

Flett Glacier refers to two glaciers on the northwestern flank of Mount Rainier in the U.S. state of Washington. The glaciers lie on a subsidiary peak of Rainier, the 8364 ft Observation Rock. There are two sections of glacial ice, an eastern lobe at about 7600 ft to 7300 ft in elevation, a smaller western lobe at about 7200 ft in elevation. Meltwater from the glacier flows into the Puyallup River.

Flett Glacier commemorates the botanist John B. Flett, who climbed Little Tahoma in 1895.
