Palmer Glacier, Extinct glacier on Mount Hood, Oregon, United States.

Palmer Glacier is an extinct glacier located on Mount Hood's south-facing slopes in Oregon, now a permanent snowfield between 6,200 and 9,300 feet elevation. The area serves as part of the Timberline ski resort where visitors can access snow terrain during spring and summer months.

This glacier was named after Joel Palmer, an Oregon pioneer, and remained active until the mid-1980s when ice movement ceased. The transition to a stationary snowfield marked the end of its existence as a moving glacier.

During the summer ski season from about May to September, the upper half of the Palmer Chairlift terrain is divided into lanes. Lanes nearest the lift are open to the public, while the others are allocated to ski and snowboard camps, ski coaches, and other organizations. The camps typically finish before public closure, allowing the public to access the entire terrain.

The Palmer Express chairlift operates during warmer months and carries skiers and snowboarders to approximately 8,500 feet elevation. Plan to bring or rent skis and snowboards, as the terrain requires winter equipment even during spring and summer.

The snowfield was long called Salmon River Glacier because it feeds the Salmon River, until a Mazama committee surveyed it on October 19, 1924 and had it mapped as a glacier. In 1981 the U.S.G.S. measured ice over 200 feet thick; by the mid-1980s movement had stopped and it was declared dead.
