The Complete History of Glacier National Park Since 1910
How Glacier went from 10,000 years of Indigenous stewardship through railroad tourism and conservation triumph to a park racing climate change.
Glacier's recorded history spans from Indigenous peoples who inhabited these mountains 10,000+ years ago, through a 25-year conservation campaign, to a park now facing unprecedented climate threats. Each era left physical marks: sacred sites, railroad lodges, the engineering marvel of Going-to-the-Sun Road, and glaciers that once defined the park but are vanishing.
- 10,000+ years Indigenous peoples lived here
- May 11, 1910 park established by President Taft
- 150 → 26 glaciers: 1910 to 2015
- 1932 Going-to-the-Sun Road completed
Indigenous Heritage: 10,000+ Years of Stewardship — Glacier region
Foundation of the parkThe Blackfeet, Salish, Kootenai, and Pend d'Oreille thrived here for millennia, establishing sacred sites and trail systems long before European arrival.
- Archaeological evidence shows continuous human presence for 10,000+ years per NPS.gov
- Blackfeet (Niitsitapi) dominated eastern prairies; territory stretched from Alberta to Yellowstone River
- Salish, Pend d'Oreille, and Kootenai inhabited western slopes, traveling seasonally across mountain passes
- Sacred sites like Chief Mountain, Two Medicine, and Many Glacier remain central to tribal creation stories
- Four tribes maintained extensive pre-European trail systems throughout the mountains
When the park was established in 1910, the boundary severed many tribes from traditional homelands without consent. The NPS now acknowledges this legacy and actively works to restore Indigenous place names and strengthen tribal partnerships with the Blackfeet Nation (whose reservation borders the park's east side) and the Confederated Salish and Kootenai Tribes.
European Exploration & the Great Northern Railway (1800s–1891) — Glacier region
Tourism catalystFur trappers arrived by the 1800s, but the railroad's completion through Marias Pass in 1891 transformed wilderness into the region's defining tourism economy.
- European fur trappers arrived in early 1800s drawn by abundant beaver; minimal permanent settlement initially
- Great Northern Railway completed through Marias Pass in 1891 at just 5,213 feet — one of the lowest passes in the northern Rockies
- James J. Hill and son Louis Hill championed the railroad and park promotion
- Swiss-style chalets built starting ~1910: Glacier Park Lodge, Many Glacier Hotel, and trail camps established the tourism infrastructure still operating today
- Marias Pass was known to Indigenous peoples for centuries before surveyor John F. Stevens' 'official discovery' in 1889; Blackfeet guides directed him there
By the 1920s, the Great Northern Railway's 'See America First' campaign made Glacier one of the most-visited parks in the country, establishing a tourism economy that sustains the region to this day.
George Bird Grinnell & the 25-Year Fight for a Park (1885–1910) — Glacier region
Founder of GlacierOne man's 25-year crusade — visiting nearly every year, writing in Forest and Stream, and lobbying Congress — created the nation's 10th national park.
- First visited St. Mary and Swiftcurrent valleys in 1885; returned nearly every year for two decades, exploring and naming landmarks
- Coined the term 'Crown of the Continent' in 1901 — capturing an intact ecosystem where prairie, forest, and glacier converge at the continent's top
- Used his magazine platform to lobby Congress, building political support for full national park status (stronger protection than forest reserves)
- Congress designated the region a forest preserve in 1897; Grinnell pushed for permanent park status to bar mining, logging, and homesteading
- President Taft signed the park bill on May 11, 1910, making Glacier the nation's 10th national park
The park honors Grinnell with Grinnell Glacier, Grinnell Lake, and Grinnell Point in Many Glacier — once among the park's largest glaciers but now dramatically diminished, a sobering monument to climate change.
The Park's Early Years & the National Park Service (1910–1932) — Glacier region
Foundation eraGlacier opened with no paved roads or visitor center; the Army managed it until the National Park Service formed in 1916, then rail tourism and trail camps drove early growth.
- When established in 1910, the park had no paved roads, visitor center, or dedicated management — the U.S. Army supervised it
- National Park Service created in 1916, six years after Glacier's founding, and assumed park management from the Army
- Early economy ran on rail tourism via Great Northern Railway to East Glacier and West Glacier stations
- Peak 1920s visitation made Glacier one of the country's most-visited parks — horse-back trips and backcountry chalets drove access
- First permanent naturalist George 'Doc' Ruhle hired in 1932; his guided hikes, campfire talks, and natural history lectures became the ranger-led template still used today
This era established infrastructure, ranger programs, and visitor culture that defined the modern park experience.
Going-to-the-Sun Road: The Engineering Marvel (1921–1933) — Glacier region
Greatest road-engineering featCarved across the Continental Divide through sheer cliff faces and avalanche zones, this 50-mile road is one of North America's greatest public works achievements.
- Construction took 11 years (1921–late 1932) requiring workers to blast through cliff faces with constant avalanche risk; three workers died
- Crosses Logan Pass at 6,646 feet — the highest point on the Continental Divide accessible by paved public road in Montana
- Cost $2.5 million (~$60 million in today's dollars) — extraordinary expense for early 20th century
- Formally dedicated July 15, 1933 at a ceremony marking its completion
- Now a National Historic Landmark and ASCE National Historic Civil Engineering Landmark
- Typically opens to full vehicle traffic in late June/early July after crews clear 60+ feet of snowpack from highest sections
Months before the road's dedication, on June 18, 1932, Glacier and Canada's Waterton Lakes were joined as the Waterton-Glacier International Peace Park — the world's first international peace park, championed by Rotary International members from both countries.
International Peace Park & UNESCO Designation (1932–1995) — Glacier region
Global recognitionWaterton-Glacier became the world's first international peace park in 1932 and earned UNESCO World Heritage status in 1995 for its extraordinary biodiversity.
- June 18, 1932: Glacier and Waterton Lakes joined as the world's first international peace park, recognizing that wildlife and watersheds cross borders
- 1995: Waterton-Glacier received UNESCO World Heritage Site designation for 'outstanding universal value'
- UNESCO citation recognizes over 300 terrestrial animal species, 250+ bird species, and 1,000+ vascular plant species
- Crown of the Continent ecosystem status: one of the most ecologically intact temperate regions on Earth
This recognition formalized Glacier's status as a globally significant protected area, though new threats emerged within decades.
The Modern Era: Glacial Decline & Climate Crisis (1995–2026) — Glacier region
Defining test of the 21st centurySince 1910, the park has lost 150 → 26 named glaciers to climate change, warming at 2x the global average, with scientists projecting total glacier loss before 2100.
- 1910: park established with ~150 glaciers; 2015: USGS confirmed only 26 named glaciers remain
- Every named glacier has shrunk since records began — average loss of 40%, some by as much as 80% of original area
- Montana's average temperature rose ~2.5°F since 1900; Glacier National Park warming at nearly 2x the global average
- U.S. EPA projections: if current trends continue, all named glaciers could disappear entirely before 2100
- Park entrance fee: $35/vehicle for 7-day pass (2026); annual visitation exceeds 3 million despite glacier loss
The park's history has thus become a story with an unresolved final chapter — from 10,000 years of Indigenous stewardship, through a century of protection and engineering triumph, to a defining test of whether the features that gave this place its name can survive the 21st century.
Common Questions
When was Glacier National Park established?
Glacier National Park was established on May 11, 1910, when President William Howard Taft signed the legislation creating it as the nation's 10th national park. It was designated following more than a decade of advocacy by conservationist George Bird Grinnell and support from the Great Northern Railway.
Who is known as the 'Father of Glacier National Park'?
George Bird Grinnell is widely credited as the driving force behind Glacier's creation. As editor of Forest and Stream magazine, he first visited the region in 1885 and spent 25 years writing and lobbying to have it designated a national park. He named many of the park's geographic features and coined the term 'Crown of the Continent' in 1901.
Why is Glacier National Park losing its glaciers?
Climate change is the primary driver. Montana's average temperature has risen approximately 2.5°F since 1900, and Glacier National Park is warming at nearly twice the global average rate. The park had roughly 150 glaciers when it was founded in 1910; only 26 named glaciers remain today, each significantly smaller than its original extent, per the U.S. Geological Survey.
What was the world's first international peace park?
The Waterton-Glacier International Peace Park was the world's first international peace park, established on June 18, 1932, when Glacier National Park (Montana, USA) and Waterton Lakes National Park (Alberta, Canada) were formally joined. The designation was championed by Rotary International members from both countries to symbolize U.S.-Canada friendship and shared conservation responsibility.
