Katsuk Glacier lies in North Cascades National Park in Washington, in a cirque north of Katsuk Peak and east of Kimtah Peak along the ridge called Jagged Edge. Set within one of the park’s rugged high mountain basins, it consists of three disconnected sections rather than a single continuous glacier. Its largest section stretches for more than 1 mile. The glacier also occupies a position between two other named glaciers in the same alpine area, with Kimtah Glacier to the west and Mesahchie Glacier to the east.
