Many Glacier is an area within Glacier National Park which is located in the U.S. state of Montana.
 The Many Glacier region is located north of the Going-to-the-Sun Road, on the east side of the park.
 Lake Sherburne is the large lake in the area and the Many Glacier Hotel, the largest hotel within the park, is along the shore of the adjacent Swiftcurrent Lake.
 The Many Glacier Hotel and surrounding buildings are a National Historic Landmark, with original construction dating back to 1915.
 Many Glacier is surrounded by the high peaks of the Lewis Range, and numerous hiking trails can be accessed from the area.
 The region is noted for numerous lakes, waterfalls and dense coniferous forests interspersed with alpine meadows. Major sites in the immediate vicinity that can be accessed by trails include Lake Josephine, Grinnell Lake, Grinnell Glacier, Cracker Lake, Granite Park Chalet, Iceberg Cirque and the Ptarmigan Tunnel, which is a hiking tunnel carved through the mountainside during the 1930s.
 Tour boats allow visitors an opportunity to venture onto Swiftcurrent Lake.
 Other activities in the region include ranger guided nature hikes, horseback riding, fishing and camping.
The Glacier National Park Tourist Trails, including the Inside Trail, South Circle Trail and North Circle Trail, were established in Glacier National Park to connect a series of tourist camps and hotels established by the Great Northern Railway between 1910 and 1915.
 Prior to the construction of the Going-to-the-Sun Road, these trails were the primary form of circulation within the park.
 The trail system includes a number of bridges.
The Garden Wall is a steep alpine area within Glacier National Park well known during the summer months to be heavily covered in dozens of species of flowering plants and shrubs.
 Located along the west side of the Continental divide and extending northward from Logan Pass, the Garden Wall can be traversed via the popular Highline Trail and for a distance of over 5 mi to the Granite Park Chalet.
 The Going-to-the-Sun Road also passes through portions of the Garden Wall northwest of Logan Pass.
 The Weeping Wall is a short stretch of the Going-to-the-Sun Road where water cascades over the Garden Wall to the roadway below.
 The Garden Wall is an arête or rock spine that separates the Many Glacier region of the park from Lake McDonald valley.
The Rising Sun Auto Camp, also known as the Roes Creek Auto Camp, East Glacier Auto Camp or simply Rising Sun preserves a portion of the built-up area of Glacier National Park that documents the second phase of tourist development in the park.
 Rising Sun is located along the Going-to-the-Sun Road, approximately 7 mi from the east entrance to Glacier National Park, Montana, United States.
 Rising Sun is a wayside area that has a National Park Service campground, a camp store and gift shop, picnic area, restaurant, as well as a motel and guest cabins which are managed by the park's concessionaire, Xanterra Parks & Resorts.
 In the immediate area, there is also a boat dock as well as sightseeing boats which allow visitors to tour Saint Mary Lake, the second largest lake in the park.
 "The most popular spot for [Glacier] tourists is Rising Sun, an overlook of Goose Island in St. Mary Lake and one of the most photographed spots in the park."
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.
The Swiftcurrent Auto Camp Historic District preserves a portion of the built-up area of Glacier National Park that documents the second phase of tourist development in the park.
 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.
 The Swiftcurrent Auto Camp at Swiftcurrent Lake was created for these new tourists.
 It includes a rustic general store, built in 1935 by the Glacier Park Hotel Company, surrounded by a number of log tourist cabins., as well as a shower and laundry house and other supporting structures.
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.
Dusty Star Mountain (8573 ft ) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.
 Connected by an arête to Citadel Mountain to the south, Dusty Star Mountain lies to the south and across the Saint Mary Valley from Going-to-the-Sun Mountain.
 Dusty Star Mountain is easily seen from the Going-to-the-Sun Road, and often photographed by tourists taking pictures of Wild Goose Island which lies in the western section of Saint Mary Lake.
 The Blackfoot name for Dusty Star is "iszika-kakatosi" meaning "meteor" or "smoking star".
Going-to-the-Sun Road is a scenic mountain road in the Rocky Mountains of the western United States, in Glacier National Park in Montana.
 The Sun Road, as it is sometimes abbreviated in National Park Service documents, is the only road that traverses the park crossing the Continental Divide through Logan Pass at an elevation of 6,646 feet (2,026 m), which is the highest point on the road.
 Construction began in 1921 and was completed in 1932 with formal dedication in the following summer on July 15, 1933.
 The road is the first to have been registered in all of the following categories: National Historic Place, National Historic Landmark and Historic Civil Engineering Landmark.
 The length of the road is approximately 50 miles (80 km) and spans the width of the park between the east and west entrance stations.
 The National Historic Landmark Nomination records a slightly shorter distance of 48.7 miles which is measured from the first main intersection just outside the park's west entrance to Divide Creek in St. Mary on the east side of the park.
