Using approximately 1,600 to 2,000 feet of hose, the city sprays mist down the bluff to create the ice sheets, at a distance Barnard said has most likely never been done before.

The water has to stay at just the right temperature to not freeze, Barnard said, but also has to lightly fall onto the rocks to create an ideal climbing surface. The park was iced over with the help of “ice farmers,” as Barnard called them, to monitor the water levels every hour for a week to create the icy terrain.

A wintry mix of snow and freezing rain, which has been common this season, can also only help the structure stay frozen, Barnard said.

The only cost to create the ice sheet is the water coming from the ground thanks to the city’s water department, Barnard said, adding that the Minnesota Climbers Association donated the hoses and equipment necessary.

Furthermore, it appears there will be no major erosion problem come springtime, something Barnard said was an initial concern among organizers and the city when discussing the idea.

“We’ve just learned so much,” Barnard said.
