I took this photo above the harsh and rugged Mt. Logan in the Montana Rocky Mountains of Glacier National Park. When folks think of glaciers the image is primarily of long rivers of frozen ice slowly creeping along into the sea. This image was captured late in the afternoon about an hour after sunset last fall before the snow season began in earnest.
These are the mountain glaciers on Mt. Jackson, specifically Pumpkin Glacier in the foreground and Pumpelly Glacier on the left hanging on the ridge, and Blackfoot Glacier on the other side of the ridge to the right.
You can see the deep turquoise blue of the ice below the snow. This image was taken in the middle of September from an altitude of 11,500 feet (3,505m). Mt Logan is 8,750 feet (2,667m) high and the glaciers are at an approximate altitude of around 8,000 feet (2,438m).
