August 25,2013 - This was the incredible view inside Mendenhall Glacier near Juneau, Alaska. After a five mile hike through bogs, forests and rock cliffs, we arrived at the cave entrance around 10am and were pleased to discover the cave to be completely empty. This shot was taken roughly 100 meters into the cave.

How this cave was formed:
As deposits of snow compress on top of itself, thick sheets of this translucent blue ice form. Over time, melting snow, rain and higher elevation glacial runoff carved this cave entrance into existence. The shape, length and location of this cave changes every year.

Thanks for looking!
