Challenger Glacier is in North Cascades National Park in the U.S. state of Washington and is on the north slopes of Mount Challenger. Challenger Glacier descends from 8000feetto5000feetft (toft).[2] Over 2miles wide, Challenger Glacier descends along a wide terminus with heavy crevassing and numerous icefalls, with a tongue of the glacier in the north descending to a proglacial lake. The ascent up Challenger Glacier is one of the most common routes to the summit of Mount Challenger.[3]
