Eel Glacier is located to the north of Mount Anderson in Olympic National Park in the U.S. state of Washington. The northward-facing glacier starts at about 6,600 feet (2,000 m) in elevation, with an arm extending up to 7,100 ft (2,200 m). As the glacier flows north, it descends in elevation to about 5,200 ft (1,600 m) at its terminus. Meltwater from the glacier gives rise to Silt Creek, which flows through the Olympic Mountains and Olympic National Park.
