Nohokomeen Glacier lies in a cirque on the north slope of Jack Mountain in North Cascades National Park, Washington. It extends from about 8,200 feet down to 6,100 feet, with a heavily crevassed surface, especially below its midpoint. Like many glaciers in the Cascades, it has been retreating, but more slowly than average. Over seventeen years its terminus receded less than one hundred yards, and over forty-six years less than nine hundred feet. During the last twenty years of retreat, a small new lake formed at about 6,260 feet. Its relatively slow shrinkage is thought to reflect its high elevation compared with many other Cascade glaciers.
