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 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 km). In 1850, there were an estimated 150 glaciers in the park. Glaciologists have stated that ...

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 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 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 balance of glaciers in and surrounding Glacier National Park. The glacier is being monitored using remote sensing equipment and repeat photography, where images of the glacier are taken from identical locations periodically. Between 1966 and 2005, Blackfoot Glacier lost over 23 percent of its surface area. In...
