Question: Going-to-the-Sun Road is a scenic route, complementing the Glacier National Park Tourist Trails, in which American mountain range?

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. <SEP> 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. <SEP>  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. 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 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. <SEP> 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.
