Glacier National Park (GNP), located in northwest Montana, US, was signed into existence on 11 May 1910 by then President William Howard Taft. Conservationist George Bird Grinnell was instrumental in lobbying for the park’s creation and negotiated the sale with the Blackfeet Indians. As an editor of the outdoor magazine Field and Stream, Grinnell learned about the region from writer James Willard Schultz and made his first visit there in 1885. Enticed and amazed by the glaciers of the area, the high Rocky Mountain alpine terrain, and the flora and fauna that thrived here, Grinnell advocated for the creation of the park, nicknaming it the “Crown of the Continent.”
Grinnell recognized glaciers as a geological wonder. As historian Gerald Diettert records in his 1992 book, Grinnell called the glaciers the “jewels” in the crown. Setting aside land to enjoy the glaciers seemed like a logical means to conserve the landscapes and ecosystems that they supported. Yet today, just about a hundred years from when the park was founded, the glaciers that form GNP’s snow-capped crown are close to extinction.

At the time of the park’s establishment, a survey by geologist Bailey Willis suggested a lack of mining and agricultural prospects, which helped with Grinnell’s conservation efforts. However, like all parks in the developing US National Park Service system, the GNP’s conservation strategies have evolved over the years. In the early days, the park’s mandate focused more on tourism than on science. By the mid-1930s, there were more concerted scientific studies. Most recently, in 2012, the National Park Service (NPS) instituted a climate change action plan and response, which includes “repeat photography” as historical documentation of glaciers over time.
Historical photographs of glaciers began to be systematically used in the United States Geological Survey’s (USGS) collaboration with GNP in 1997. They provide a visual representation of glacier retreat. When combined with other types of geological information, such as USGS mapping and fieldwork, they help pinpoint the changing park landscape.

Geological records suggest that 150 glaciers existed in 1850. Today, the USGS reports that only 25 glaciers are currently recognized as “active”—that is, big enough (0.1 km2 or approximately 25 acres) to showcase the classic dynamics of movement we associate with glaciers.
It is important to note that glaciologists expected to see the park’s glaciers retreat from their 1850 extent. In fact, early investigations showed that glaciers had retreated from their maximum extent even at the time of the park’s establishment. This finding made scientific sense since geological records mark 1850 as the end of the Little Ice Age, a period of global cooling that began in the 1400s in North America, and had favored the growth of the glaciers.

However, what is alarming to geologists and park managers working on the historical, scientific, and recreational value of the park’s glaciers is the recent rapid rate of retreat. Climate model simulations reported by geologists Myrna Hall and Daniel Fagre in 2003 suggest that by 2030 GNP might be devoid of glaciers. USGS observations of actual rates of glacial retreat suggest this reality might come sooner than 2030.
The loss of glaciers has a cascade effect on the entire region, from water supply concerns to the struggle by species to adapt or perish with the changing landscape and climate conditions. While global temperature trajectories do not bode well for the park’s glaciers, interdisciplinary studies that combine visual history with science give the reality of climate change a “face.” Like the writings of GNP’s early conservationists—Schutz, Grinnell, and Wallis—these images can evoke environmental concern, and in this case, fuel legislative action to curb anthropogenic climate change.
