All I have to say is, “WOW.”
I’ve been to the face of the Mendenhall Glacier, but I’ve never been lucky enough to discover a glacier cave until now and I definitely understand why people get so excited about them.
It was amazingly bright no matter how far from the entrance you got. Light somehow found its way through the mass of ice above, which filtered out all but the blue light and gave an eerie glow everywhere you looked. I had a field day snapping photos and constructing makeshift camera platforms from rocks. These are the best in my opinion – enjoy!
