Freezing temperatures means crews have begun work on Lake Geneva Ice Castles.

Workers have begun growing the process of growing icicles, with about 10,000 icicles being harvested each day, according to a release. The entire process will take 4,000 hours to create the ice and embed the structures with LED lights.

This year’s castles in Lake Geneva will feature ice-carved slides, tunnels, fountains, crawl spaces and more, organizers said.

Ice Castles said in a release Tuesday that the attraction will be open by mid-December.

Lake Geneva is one of six Ice Castles locations in North America. Other locations include Midway, Utah; Excelsior, Minnesota; Lincoln, New Hampshire; Dillon, Colorado; and Edmonton, Alberta.
