Context paragraphs:
Glacier Park Company: The Glacier Park Company, a subsidiary of the Great Northern Railway (GN), constructed and operated hotels, chalets, and other visitor facilities in Glacier National Park, Montana and Waterton Lakes National Park, Alberta from the 1910s through 1960.  Operating as a concessionaire of the National Park Service, the company operated from a summer base in East Glacier Park, Montana, near the company's flagship Glacier Park Hotel; winter headquarters were in St. Paul, Minnesota.  Originally known as the Glacier Park Hotel Company, the corporate name was shortened to Glacier Park Company in 1943.

Montana Highway 49: Highway 49 in the U.S. State of Montana is a route running in a northerly direction from a junction with U.S. Route 2 in the town of East Glacier Park.  The highway extends approximately 12 mi to an intersection with U.S. Route 89 at a location known as Kiowa.  Highway 49 is near the southeastern corner of Glacier National Park, and is heavily used by tourists during the summer months.  A spur road heading west from Montana 49 four miles (6 km) north of East Glacier provides access to the Two Medicine area of the park.

Glacier Park Lodge: Glacier Park Lodge is located just outside the boundaries of Glacier National Park in the village of East Glacier Park, Montana, United States.

Swiftcurrent Auto Camp Historic District: 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.

The chalet originally featured a complex of log buildings, all built in the rustic style, which provided dining and lodging facilities.

The coffee shop was built in 1965 as part of the National Park Service's Mission 66 program to upgrade visitor facilities, in order to increase visitor dining capacity.  Under the Mission 66 projects, visitor facilities were usually comprehensive in nature, providing a range of visitor services.  Specialized concession buildings like the Coffee Shop were unusual in Mission 66.  It was leased to the Glacier Park Company for operation, in anticipation of the construction of lodging facilities by the company.

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 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.
