Building an ice tower in Alaska

 Images Ice-Wall-04-05 IceheadeThe Alaska Alpine Club in Fairbanks decided to build a 132-tall ice tower. They used a rotating nozzle that sprayed water, making a kind of giant, upside down icicle. The pictures of the tower are neat, but I was even more impressed with the photos of the home made nozzles they used to make the tower.
