File:Athabasca Glacier Runoff.jpg
From Global Warming Art
Downcutting of ice due to the melt water flow is clearly visible in this image. Similar downcutting can aid in the creation of crevasses, such as contributed to the breakup of the Larsen B Ice Shelf. When the water in channels such as this manages to reach the underside of the glacier, it can also cause glacial flow to significantly increase by virtue of lubrication.
