Nooksack Cirque is in North Cascades National Park in the U.S. state of Washington, on the eastern slopes of Mount Shuksan.[2] Nooksack Cirque was formed by glaciers and the East Nooksack Glacier is located in the cirque below the headwall known as Jagged Ridge. The cirque extends from a subpeak of Mount Shuksan called Nooksack Tower to Seahpo Peak, a distance of over 2miles in width.[1] Nooksack Cirque streams and meltwater from the East Nooksack Glacier form the headwaters for the Nooksack River.
