Glacial thinning and retreat
This photo pair features the toe of the Kahiltna Glacier, with the Yenlo Hills visible in the distant left of the more recent photo. In 1916, the Kahiltna glacial ice extended beyond the left side of the frame and the surface had large bands that were relatively free of sediment. By 2004, the glacier had retreated up-valley and much of its surface was covered in sediment. What do you think will happen next assuming this glacier will continue to thin and retreat? Hint: Look at photo pairs of other glaciers.
