Jackson Glacier

[2] A part of the largest grouping of glaciers in the park, Jackson Glacier rests on the north side of Mount Jackson.

Between 1966 and 2005, Jackson Glacier lost almost a third of its acreage.

Glaciologists have stated that by the year 2030, many if not all of the glaciers in the park may disappear completely.

The glacier is being monitored using remote sensing equipment and repeat photography, where images of the glacier are taken from identical locations periodically.

[5] Jackson Glacier is one of the easiest of the park's glaciers to observe, and is located south of the Going-to-the-Sun Road on the east side of the Continental Divide, upper St. Mary Valley.

The upper image shows how Blackfoot (on the left) and Jackson Glaciers (on the right) appeared in 1914. The lower image is taken from the same vantage point in 2001.
Jackson Glacier at right was once joined to Blackfoot Glacier on the left.
