Old Sun Glacier, Alpine glacier in Glacier National Park, Montana.
Old Sun Glacier extends between 8,600 and 9,400 feet in elevation, covering 91 acres near Mount Merritt in Glacier National Park.
Between 1966 and 2005, this glacier experienced a reduction of 12 percent in its surface area due to environmental changes.
The glacier received its name from a Blackfoot sun priest called Ntas, reflecting the Native American connections to this land.
Climbers accessing Old Sun Glacier need technical equipment including ropes, ice axes, and crampons for safe glacier traversal.
The glacier features multiple crevasses and maintains an accumulation zone while terminating in a natural rockfall formation.
