Traleika Glacier, Glacier in Denali National Park, Alaska.

Traleika Glacier is a glacier in Denali National Park and Preserve, Alaska, formed by two forks on either side of Farthing Horn, east of Denali. The west fork begins in Thayer Basin at about 4,600 m and drops through the Traleika Icefall between Karsten Ridge and Farthing Horn. The main fork starts in Traleika Col on Denali's east buttress and joins the west fork between Farthing Horn and Mount Silverthrone, then flows northeast into Muldrow Glacier.

Bradford Washburn named this glacier in 1945 after a Susitna term meaning 'great one' or 'high one'. This naming was part of Washburn's systematic mapping work across Alaska's mountain ranges during that period.

Bradford Washburn named the glacier in 1945, taking Traleika from the Dena'ina name Dghelaay Ka'a, which denotes Denali itself. The same word was recorded as a Susitna term meaning "great one" or "high one". The glacier therefore carries an Athabascan place name for the mountain it drains, anglicised on maps.

Traleika Glacier lies on the east side of Denali, reached from the Thayer Basin at 4,600 m via the Traleika Icefall, or from Traleika Col on Denali's east buttress. Access is by ski plane or a long glacier expedition; the west fork joins the main fork between Farthing Horn and Mount Silverthrone before flowing northeast into Muldrow Glacier.

The west fork begins in Thayer Basin at about 15,000 feet (4,600 m) and drops through the Traleika Icefall into the fork between Karsten Ridge and Farthing Horn. The main fork starts in Traleika Col on Denali's east buttress and joins the west fork between Farthing Horn and Mount Silverthrone.
