WOODSTOCK, N.H. (CBS) – Construction is underway at the popular ice castles in New Hampshire.

Artists are hand-placing 10,000 icicles a day to help bring the winter attraction to life.

There will be ice-carved slides, tunnels and crawl spaces.

Organizers are hoping to open in early January, weather permitting.

A limited numbers of priority booking vouchers go on sale Monday for anyone who wants early access to tickets.
