Description:
This photo pair was taken looking up the Muldrow Glacier to the summit of Mt. McKinley. Can you see changes to this wintry landscape? There are many photo pairs of the Muldrow Glacier obtained in this project, and it is interesting to note how the pace of change has been different along its 34 mile length. Why do you think that is?
