Inspiration Glacier lies on the east slopes of Eldorado Peak in North Cascades National Park, Washington, high in a cirque bordered by Eldorado Peak, Tepeh Towers, and Klawatti Peak. About 1.5 miles long and about 2 miles wide at its terminus, it descends from roughly 8,500 feet to 6,800 feet. The glacier connects to Eldorado Glacier on the south side, while Tepeh Towers partly separates it from McAllister Glacier to the north. Its meltwater drains into Moraine Lake.
