We are on a road trip to Idaho. Khloe is skating in the Sun Valley Figure Skating Championship. (Or something like that) It is about 4 1/2 hour drive. On the way about 45 minutes outside of Ketchum there are some caves made from lava tubes from an internal eruption of a volcano a couple million years ago. I looked at two different caves and we chose the Shoshone ice cave. It is a cave where they discovered ice in the cave when they blasted out a wall in the 1800's. When they blasted the wall it changed the airflow and the ice started to melt. Somewhere along the line scientist figured out what the problem was and they sealed the cave. Now it forms about 12 inches of new ice a year. It would be faster but the tours in the summer use lights and the opening of the door messes up the air flow. It's 26 degrees year round in the cave. |
