Blackfoot Glacier is the largest of the remaining 27 glaciers in Glacier National Park. The glacier was most recently measured in 1993 at 430 acres (1.74 km²), yet when first documented in 1850, the glacier also included the now separate Jackson Glacier and together, they covered 1,875 acres (7.59 km².) Blackfoot Glacier is retreating rapidly, as are all of the glaciers in the park. 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 will cease to be glaciers and instead will either vanish or be reduced to ice filled snowfields.
