Greenland ice sheet trimline



A fabulous photo of the edge of the Greenland ice sheet, showing a very prominent trimline between a landscape of weathered rock and reasonable vegetation cover, to the left, and a landscape of newly exposed and "clean" rock in the centre of the photo.  On the lower version of the image I have added one white line for the position of the trimline, and another showing the current ice edge.  Sadly, I don't have info on the length of time that has elapsed between the advanced ice edge position and that of the present day.....

The image is from somewhere in SW Greenland.
