Blackfoot Glacier is the second largest of the remaining 25 glaciers in Glacier National Park
and is located to the north of Blackfoot Mountain
. The glacier was most recently measured in 2005 at 441 acres (1.78 sq km), yet when first documented in 1850, the glacier also included the now separate Jackson Glacier
and together, they covered 1,875 acres (7.59 sq km).
In 1850, there were an estimated 150 glaciers in the park. Glaciologists have stated that by the year 2030, all the glaciers in the park may disappear. Jackson
and Blackfoot glaciers have been selected for monitoring by the U.S. Geological Survey's Glacier Monitoring Research program, which is researching changes to the mass balanceof glaciers in and surrounding Glacier National Park.
