Question: The Big Drift is in Glacier National Park, in the U.S. state of Montana, and is an area along which scenic mountain road in the Rocky Mountains of the western United States, in Glacier National Park in Montana?
Context: The Big Drift is in Glacier National Park, in the U.S. state of Montana and is an area along the Going-to-the-Sun Road where a large amount of winter snow can accumulate to depths of 80 ft .  Located immediately east of Logan Pass, the westerly winds push snow over the crest of the Continental Divide onto the eastern flank of a long arête which extends south from Pollock Mountain.  West of the divide, this arête is known as the Garden Wall. The Chief Mountain Border Station and Quarters is a customs station on the Canada–United States border in Glacier County, Montana.  Located on Montana Highway 17, the station is operated seasonally, primarily for tourist traffic between Glacier National Park in Montana and Waterton Lakes National Park in Alberta.  The station is named after Chief Mountain, a prominent peak in the vicinity.  The station is owned by the General Services Administration and operated by the U.S. Customs Service, and is located within the boundaries of Glacier National Park.  The station is a notable example of the National Park Service Rustic style and is listed on the National Register of Historic Places. 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.

Shepard Glacier is a glacier remnant (glacieret) In Glacier National Park in the U.S. state of Montana.  The glacieret is immediately southeast of Cathedral Peak.  Shepard Glacier was one of a number of glaciers that have been documented by the United States Geological Service (USGS) to have retreated significantly in Glacier National Park.  Shepard Glacier was measured in 2009 to have decreased to less than 25 acre , considered to be a minimal size to qualify as being considered an active glacier.  Between 1966 and 2005, Shepard Glacier lost 56 percent of its surface area. 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. 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. 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. 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. 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."
Answer: Going-to-the-Sun Road
