Natural wonders of the world can be truly mind-boggling. Man-made objects are only so powerful, until they meet their eventual maker: nature itself.

In parts of Utah, Colorado, and New Hampshire, the perfect juxtaposition of man-made and nature exists in the form of massive ice sculptures. These formations were actually part of a larger project called Ice Castles—made from 20,000,000 pounds of ice, these magnificent creations were built by people and widely explored.

The structures are comprised of a combination of icicles and freezing water, modified by wind and varying temperatures. Creator Brent Christensen had the idea for the project after putting together an elaborate ice-skating rink in his backyard for his family, complete with a slide, cave, and ice castle. The result is a strange and magical phenomenon.
