It seems to me that humans, like ravens, have an almost uncontrollable attraction to 'bright shiny things.' We buy shiny packages and cover everything from our buildings to our bodies with bright, reflective materials. Well, let me tell you, a good ice cave is irresistible. You stand on the outside and think, “What am I doing?! It's melting! Water is dripping from the roof! It's a glacier! The ice is moving! Only a crazy person would go in there!” But you go in. You have to. It is the ultimate bright and shiny thing, and you are inside it... Photographer: Bill Eichenlaub
