Ice cave on Boulder Glacier, Glacier National Park.
This pairing of photos from the flank of Boulder Glacier reveals a dramatic change in the 56 years between the photos. The repeat photograph was taken by Glacier National Park ranger Jerry DeSanto. Pack trips to Boulder Glacier used to include exploration of the glacier’s ice cave. The cave has long since disappeared as the glacier receded beyond this point.
