Work crews were able to get the pipe in primo condition for skiers and riders, to start off the New Year, after record-setting snowfall in December. The SuperPipe stretches out to 450 feet long with 18-foot walls. It is also down the hill more, closer to the lift so skiers and riders can take more laps. Magazines like TransWorld Snowboarding and Freeskier have all ranked the A51 Terrain Park in the top ten in the country before. You can give it a shot under the lights. The SuperPipe is also open for night jibbing at Keystone. It's Colorado's largest and only night park.
