The glacier was most recently measured in 2015 at , yet when first documented in 1850, the glacier also included the now separate Jackson Glacier and together, they covered . 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.
However, under a modest increase in overall
carbon dioxide levels, some glaciers will remain until the late 23rd century.

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
