Dixon Glacier is located in the U.S. state of Montana in Glacier National Park. The glacier is situated in a cirque immediately to the north of The Sentinel at an elevation between 8,500 feet (2,600 m) and 7,400 feet (2,300 m) above sea level. Immediately east of the Continental Divide, the glacier is 1 mi (1.6 km) east of Thunderbird Glacier. [3] Dixon Glacier covers an area of approximately 59 acres (0.24 km2) and between 1966 and 2005 lost over 45 percent of its surface area. [2]
Harrison Glacier is a glacier located in the US state of Montana in Glacier National Park. Situated on a southeast‐facing ridge immediately south of Mount Jackson, it is the largest remaining glacier in Glacier National Park, estimated in 2005 to have an area of 466 acres (1.89 km2). Though many experts have stated that all the glaciers in Glacier National Park may disappear by the year 2030, Harrison Glacier lost only 9 percent of its surface area in the 40-year period between 1966 and 2005 and will likely still exist well beyond 2030. Compared to many of the vanishing glaciers in Glacier National Park, Harrison Glacier's accumulation zone is at a much higher altitude, which has allowed it to maintain some equilibrium in its glacier mass balance. Comparisons of images of the glacier taken in 1913 with images from 2009 indicate that the glacier has experienced thinning and retreat.
Ahern Glacier is in Glacier National Park in the U.S. state of Montana. The glacier was named after George Patrick Ahern. Ahern Glacier is situated on a ridge between Ipasha Peak to the north and Ahern Peak to the south at an elevation between 8,800 feet (2,700 m) and 8,000 feet (2,400 m) above sea level, immediately east of the Continental Divide. Meltwater from the glacier feeds Ahern Glacier Falls, a waterfall which descends an estimated 1,680 feet (510 m) in one sheer drop to a talus slope below en route to Helen Lake. Between 1966 and 2005, Ahern Glacier lost 13 percent of its surface area.
