Margerie Glacier, Alaska
Margerie Glacier is a 21 mi (34 km) long tidewater glacier in Glacier Bay, Alaska. Margerie Glacier has a total height of 350 feet (110 m) of which 250 feet (76 m) rises above the water level and 100 feet (30 m) is beneath the water surface.[2] Like many glaciers it contains moraines which appear as dark areas composed of dirt, stones and larger rocks mixed in with the ice and transported downstream to eventually be ejected from the glacier's terminus. The glacial ice appears blue as a result of the absorption of red, orange, yellow and green wavelengths of light and, consequently, pools of meltwater on top of the glacier will appear bright blue.
