Two 20-inch-wide chutes are side-by-side on tracks that are refrigerated with a cooling unit and a pump. We learned from facts that were posted at the site that the pump carries cooled diethylene glycol through an underground piping system to the chutes. The diethylene glycol chills the concrete and allows the water on the surface to freeze. This is what allows riders to glide safely and quickly down the hill!
