Don’t wait to visit Montana’s Glacier National Park before it loses its glaciers!
U.S. Geological Survey data sows the park’s 37 glaciers, along with two others have shrunk 40% since 1966.
The survey goes on to show, there is no doubt that they will be gone in our lifetime. In order for the glaciers to survive, the area would need to experience “significant cooling.” Likely, it is already too late for the glaciers to survive.
A project with Portland State University geologist Andrew G. Fountain measured the glaciers’ deterioration using aerial photography over the last 50 years, along with several satellites.
The project determined that the masses deteriorated so much, they are no longer large enough to even be considered glaciers. A glacier is considered to be a mass of ice that is at least 25 acres. Some of the glaciers at the park actually lost 85% of their mass.
The park’s glaciers are estimated at 7,000 years old and “peaked” in the 1800s during the “Little Ice Age.” In 1850, the park had an estimated 150 glaciers. Since then, it lost about 85% of its ice area and now has less than 30 glaciers.
