Grain silos used by rural mountain climbers

Don Briggs came up with the idea several years ago. He
sprays
the silos with
water during the winter, turning them into glistening towers of ice that draw
hundreds of climbers from across the Midwest, as well as China, Canada and
Alaska.

During most weekends between November and March, Briggs can be found at
the silos, scaling the ice and helping others learn to climb. He has written a
book on ice climbing and been featured in climbing magazines. He also teaches a
course on the sport at the University of Northern Iowa.
