Alive – Photograph and caption by Jonathan Tucker. National Geographic Your Shot – This is a self portrait I took of my self. This photo was taken under a glacier in Alaska. I hiked over two hours through swamps and up the side of a mountain to reach the Glacier itself..I spent around a hour walking on top of the glacier taking photos until I found this cave. The cave is formed from a water fall from the mountain that meets the glacier.When I first walked in the cave it took my breath away it was so amazing and scary at the same time especially when you hear the ice crack.
