In this Wednesday, Jan. 8, 2014 photo, patrons tour an ice castle at the base of the Loon Mountain ski resort in Lincoln, N.H. The ice castle begins to grow in the fall when the weather gets below freezing and thousands of icicles are made and harvested then placed around sprinkler heads and sprayed with water. The castle will continue to grow as long as the temperatures stay below freezing. (AP Photo/Jim Cole) Jim Cole
