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.
 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.
Harrison Glacier is located in the US state of Montana in Glacier National Park.
 Situated on a southeast facing ridge immediately south of Mount Jackson, Harrison Glacier is the largest glacier in Glacier National Park and was estimated in 2005 to have an area of 466 acre .
 Though many experts have stated that all the glaciers in Glacier National Park may disappear by the year 2030, Harrison Glacier lost only 9 percent of its surface area in the 40-year period between 1966 and 2005 and will likely still exist well beyond 2030.
 Compared to many of the vanishing glaciers in Glacier National Park, Harrison Glacier has a much higher altitude accumulation zone (approximately 9000 ft ) which has allowed it to maintain some equilibrium in its glacier mass balance.
 Comparing images of the glacier taken in 1913 with those from 2009, indicates that the glacier has experienced thinning and retreat.
Mount Jackson (10052 ft ) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.
 Mount Jackson is the fourth tallest mountain in Glacier National Park and it is situated on the Continental Divide.
 Both the mountain and its namesake Jackson Glacier are easily seen from the Going-to-the-Sun Road.
 On the southern flanks of Mount Jackson is Harrison Glacier, the largest remaining glacier in the park.
The Glacier National Park Fund (established in 1999), is an organization whose main goal is to raise money to support the demands of the Glacier National Park, located in West Glacier, Montana.
 According to the National Park Service, the Glacier National Park Fund supports park projects, programs, and services in four areas: to preserve the park experience, to provide curriculum-based instruction, to research the park ecosystem, and to prepare for the 2010 Centennial year of the park.
 The Glacier National Park Fund provided funds for different studies.
 In July 2007, The Glacier National Park Fund funded a study involving human and bear aversion techniques.
 Also, in 2009, The Glacier National Park Fund granted $10,000 to enable biologists to learn more about the Bighorn Sheep that inhabit Glacier National Park, along the park's boundary with the Blackfeet Indian Reservation.
 The Glacier National Park Fund has an official mascot named Billy Bowman.
Montana is a state in the Western United States.
 The western third of Montana contains numerous mountain ranges.
 Smaller, "island ranges" are found in the central third of the state, for a total of 77 named ranges of the Rocky Mountains.
 This geographical fact is reflected in the state's name, derived from the Spanish word "montaña" (mountain).
 Montana has several nicknames, none official, including: "The Treasure State" and "Big Sky Country", and slogans that include "Land of the Shining Mountains" and more recently, "The Last Best Place".
 The state ranks fourth in area, but 44th in population, and accordingly has the third-lowest population density in the United States.
 The economy is primarily based on services, with ranching, wheat farming, oil and coal mining in the east, and lumber, tourism, and hard rock mining in the west.
 Millions of tourists annually visit Glacier National Park, the Little Bighorn Battlefield National Monument, and three of the five entrances to Yellowstone National Park.
