Located in Kenai Fjords National Park in the Kenai Mountains of Alaska, the three mile long Exit Glacier "pours" 2,500 feet down out of the Harding Icefield. At the base is Exit Creek, fed by the melting glacier. The glacier served as an "exit point" for the first recorded crossing of the Harding Icefield in 1968 and thereby got its name.
There are blue portions of the glacier that are a result of compressed snow combining with the glacier as it makes its way towards the creek. Air bubbles in the ice are forced out, increasing the size of the ice crystals which allows it to absorb most light, reflecting the short-wavelength blue light.
