❄️ Jackson Glacier

Jackson Glacier is approximately the seventh largest of the remaining 25 glaciers in Glacier National Park located in the US state of Montana. A part of the largest grouping of glaciers in the park, Jackson Glacier rests on the north side of Mount Jackson. The glacier was most recently measured in 2005 at 250 acres (1.0 km2), yet when first documented in 1850, the glacier also included the now separate Blackfoot Glacier and together, they covered 1,875 acres (7.59 km2). Between 1966 and 2005, Jackson Glacier lost almost a third of its acreage. When the two glaciers were united prior to their separation sometime before 1929, they were known simply as Blackfoot Glacier.
