 Originally known as the Glacier Park Hotel Company, the corporate name was shortened to Glacier Park Company in 1943.

 After the creation of a series of hotels for train-borne visitors including the nearby Many Glacier Hotel, courtesy of the Great Northern Railway's hotel concession, facilities were developed for the increasing numbers of automobile-borne tourists, drawn to Glacier by the Going-to-the-Sun Road.

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 acre , yet when first documented in 1850, the glacier also included the now separate Blackfoot Glacier and together, they covered 1875 acre .
 Between 1966 and 2005, Jackson Glacier lost almost a third of its acreage.
 When the two mountains were united prior to their separation sometime before 1929, they were known simply as Blackfoot Glacier.
 In 1850, there were an estimated 150 glaciers in the park.
 Glaciologists have stated that by the year 2030, many if not all of the glaciers in the park may disappear completely.
 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, where images of the glacier are taken from identical locations periodically.
