Thousands of people are flocking to a winter wonderland constructed from ice in New Hampshire.
Ice Castles in North Woodstock features a collection of ice tunnels, caverns and a 97ft ice slide that cover an acre of farmland.
The scene – one of six in North America – starts small in December when a team sets up icicle farms: metal racks sprayed with water to allow icicles to grow overnight.
The team then harvests the icicles and continually sprays them with water.
