Glaciers

This week I visited Glacier National Park in Montana. When the park first opened in 1914 there were over 100 glaciers. In 1966, there were 35 active glaciers. Today, in 2019, there are only 26 considered large enough to be active. Although the glaciers there are stunning, beautiful, bright blue (from the compression of all that ice), and bigger than you can imagine, they are nearly all melting. At Glacier National Park there are U-shaped valleys, hanging valleys, moraines, aretes, and more, all formed by the moving glaciers!

Above, you can see the Sperry Glacier, one of the glaciers at the National Park. You'll notice that the left image (from 1930) has many more peaks and much more snow that the right image (2008).
