Alsek Lake icebergs
We spent two nights on Alsek Lake. It was great going out rafting around the icebergs. we collected some ice out of the lake. Nothing like a mixed drink with 3000 year old ice. A few hours after rafting by the Iceberg with the cave we heard a rumble and looked over from our camp and the cave fell into the lake. Tons of ice came down and the cave area no longer exists. Why we did not get real close to the icebergs.
