Keyhole Unlocks This Glacier

Margerie Glacier; Glacier Bay National Park, Alaska ...
The distances are so vast and sizes are so massive, it is easy to lose accurate perspective. Nothing seen here is small or close. The centered ice feature is as big as a couple of houses (and will collapse into the bay in no more than a few days); the black ridge to the left is about 2.5Km distant; the mountains in background are about 15-20Km distant.
