Why Glacier National Park
Glacier National Park is located in northwestern Montana along the border between the United States and Canada. Spanning over one million acres, the park encompasses portions of two Rocky Mountain sub-ranges, the Lewis and Livingston ranges, and contains more than 130 named lakes. It serves as the core of the vast protected area known as the Crown of the Continent Ecosystem. Bordering Canada's Waterton Lakes National Park to the north, the two reserves together form the Waterton-Glacier International Peace Park. The combined territory holds recognitions as a World Heritage Site, a UNESCO Biosphere Reserve, and an International Dark Sky Park.
The topography of the region was largely carved by ancient geological events and massive glacial erosion. The park's mountains were formed roughly 170 million years ago when older sedimentary rock was forced over younger strata, creating the Lewis Overthrust, which contains notable early life fossils. Although an estimated 150 glaciers existed in the park during the mid-19th century, only 25 active glaciers remained by 2010. The environment encompasses diverse ecosystems ranging from prairie to alpine tundra, including forests of hemlock and western redcedar in the southwestern district. Almost all native plant and animal species persist within the park, which provides habitat for large mammals like grizzly bears, black bears, moose, elk, bighorn sheep, and mountain goats, as well as predators such as gray wolves, mountain lions, wolverines, and Canadian lynx.
Human history in the area includes long-standing Native American presence, with early inhabitants including the Salish, Kootenai, Cheyenne, Shoshone, and Blackfeet tribes. To the Blackfeet, the eastern mountains, particularly Chief Mountain and Two Medicine, held deep spiritual significance. In 1895, the Blackfeet sold the mountainous section of their reservation lands to the United States government. Following conservation advocacy led by figures such as George Bird Grinnell, the area became a national park on May 11, 1910. Shortly thereafter, the Great Northern Railway constructed a series of backcountry trails, tent camps, and Swiss-inspired lodges—including Many Glacier Hotel and several chalets—to attract railroad passengers. Hundreds of historic buildings, ranger stations, and surviving rustic chalets remain preserved today on the National Register of Historic Places.
A major feature for visitors is the Going-to-the-Sun Road, a 53-mile highway completed in 1932 that cuts through the interior of the park and traverses the Continental Divide at Logan Pass. Along the southern border, U.S. Route 2 crosses Marias Pass, linking the gateway communities of West Glacier and East Glacier. Headquartered in West Glacier, the park is administered by the National Park Service, which balances millions of annual visitors with strict preservation mandates that forbid hunting, logging, and mining. Fire is also an integral component of the park's natural cycle, with forest fires occurring nearly every year since the reserve was established.
