This is what really old ice looks like. A little different from the piles you see around Telluride Town Park in the springtime. We actually had a chance to see a large peice of this glacier "calve" into the lake while we were eating cream cheese and salami sandwiches for lunch. The sound is a lot like a thunder clap mixted with an air force fighter jet. The wall of ice is probably about 100 ft. high out of the water.
