Man turns on sprinklers to create a tower of ice

John Reeves is dwarfed as he walks by the nearly 150-foot Fox Ice Tower outside Fairbanks. Reeves began work on the tower in October when he set up a sprinkler system and pumped water through it. He guesses the tower will be 160 to 180 feet tall and weigh an estimated 80,000 tons by April, when he plans to turn off the water to the sprinklers.

How cool is that!!!! The full story is here, and there are some more pictures here.
