Harrison Glacier,Montana,USA in 2009. Image 2 of 2. Harrison Glacier is the largest glacier within Glacier National Park. Glaciers are large,slow-moving expanses of ice,formed from compacted layers of snow. They are sensitive to climate change and in recent years most have retreated dramatically. In 2009,the glacier appears to have visibly receded,exposing more rock surface compared to an image from the same position taken in 1913 (C014/5111) | |
