Ahern Glacier, Glacier in Glacier National Park, Montana, United States

Ahern Glacier lies on a ridge between Ipasha Peak to the north and Ahern Peak to the south, immediately east of the Continental Divide in Glacier National Park, Montana. Its ice surface runs from about 8,800 feet (2,700 m) down to 8,000 feet (2,400 m) above sea level. Meltwater from the glacier feeds Ahern Glacier Falls, which drops an estimated 1,680 feet (510 m) in one sheer plunge to a talus slope on its way to Helen Lake.

This glacier was named after George Patrick Ahern, a Lieutenant Colonel in the United States Army. The National Park Service assigned the name as part of mapping the protected park lands.
