Crook Glacier is a glacier in Oregon’s Cascade Range, occupying a cirque just south of Broken Top, an extinct stratovolcano. It lies high on the mountain, extending from about 8,700 feet down to about 8,000 feet, with elevations also given as 2,700 to 2,400 meters. Its significance is tied to its position on the slopes of Broken Top within the high volcanic landscape of the Cascades.
