Environmental Graffiti blog has a pretty neat post about frozen waterfalls - this one is a photo of an ice climber scaling The Fang in Vail, Colorado:
The enormous ice pillar forms from the cascading waterfall only on exceptionally cold winters, and when it does the column can measure up to 50 meters high and has been known to have a base measuring 8 meters wide.
Zing! *ba dump tish!*
