LINCOLN, N.H. (January 13, 2014) At Loon Mountain in Lincoln, Neb., thousands of icicles have been grown, picked and assembled to create an ice castle not unlike the palace in the Disney movie "Frozen."
It's one of three ice castles being built this winter.
The others are in Breckenridge, Colo., and Midway, Utah.
Brent Christensen started his Ice Castles company a few years ago after building elaborate slides and ice towers for his children in the backyard of his home in Utah.
The process of creating an ice castle involves spraying water onto metal racks to produce icicles that are stuck to the ground around sprinkler heads.
After a few weeks, towers, tunnels, archways and caves emerge.
