Photographer Aaron Huey, who is on assignment for National Geographic, recently shared a picture of a frighteningly deep hole on the Lower Ruth Glacier. The only thing stopping people from plummeting down the 304.8m drop into the ground is a sheet of ice. One crack, though.
Staring down what could be a 1,000ft deep worm hole through the blue ice of the Lower #RuthGlacier. I was never afraid of the ones full of water, they'd just be cold, but some had no water and it was easy to imagine a long slide to an icy death. #yikes (on assignment for @natgeo in #DenaliNationalPark)
