Collier Glacier is in the U.S. state of Oregon. The glacier is situated in the Cascade Range at an elevation generally above 8,000 feet (2,400 m). Collier Glacier is on the west slopes of North Sister, an extinct shield volcano. Since its last maximum extent during the Little Ice Age (1350–1850 A.D.) the glacier has retreated over a mile.
