Palmer Glacier is the most well-known of the twelve glaciers on the mountain, and is a popular destination for snow sport enthusiasts. Some of the lower part is within the Timberline ski area, and can be accessed by Sno-Cat or by chairlift, conditions permitting.

The glacier is a remnant of the massive glaciers that formed during the last ice age, and is the only location in North America that provides skiing and snowboarding all twelve months of the year.

The glacier was considered a snow field until a Mazama committee [The Mazamas committee consisted of Rodney L. Glisan, L. A. Nelson, Earl A. Marshall, Raymond Smith, Fred McNeil, Everett Philpoe, T. Raymond Conway, and Fred W. Stadter.] investigated on October 191924 and determined it was, in fact, a glacier and should be named on maps. For some time after that it was known as Salmon River Glacier as it is the headwaters of the Salmon River. [ cite book

Silcox Hut, a warming hut for climbers and skiers, is located near the base of the glacier, about 1,000 vertical feet (305 m) up from Timberline Lodge near the upper terminal of the Magic Mile ski lift.

The glacier is bounded on the east by a ridge shared with White River Canyon (which contains White River Glacier) and on the west by Zigzag Glacier and Zigzag Canyon, the source of the Zigzag River. The upper glacier narrows to a vertex near the base of "Steel Cliff", an area known as "Triangle Moraine". Below the glacier, its snowfield varies significantly seasonally, varying in length by almost two miles (3.2 km.) During the summer ski season (approximately May through September), the upper half of the "Palmer Chairlift" terrain is divided into lanes (visible in photo) for the same reason as a lap swimming pool. The lanes beside the lift are open to the public; the others are allocated to ski and snowboard camps, coaches and other organizations.
