Blackfoot Glacier is the second largest of the remaining 25 glaciers in Glacier National Park Montana. Blackfoot Glacier is just to the north of Blackfoot Mountain and near Jackson Glacier. The glacier was most recently measured in 2005 at 441 acres (1.78 km2) yet when first documented in 1850 the glacier also included the now separate Jackson Glacier and together they covered 1875 acres (7.59 km2). In 1850 there were an estimated 150 glaciers in the park.
