Eel Glacier is located to the north of Mount Anderson and east of West Peak, in Olympic National Park in the U.S. state of Washington.

[2] 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.

[2] Between 1920 and 2009, Eel Glacier has retreated significantly, losing 50 percent of its surface area.

[3] Eel Glacier's name was obtained by taking mountaineer Fairman B. Lee's last name and spelling it backwards.
