The big storms pounded the northwest Colorado resort all winter, resulting in epic ski conditions for the mountain. Steamboat has received 452 inches or over 37.5 feet of snow, at press time. That's the height of a good-sized building. The amazing thing is Steamboat had to delay its opening nine days because there wasn't any snow. But that all changed. Many resorts are staying open longer this season, but Steamboat still will close April 6. Mountain officials say that's because demand drops off, employee visas run out, and flights in and out of town drop dramatically Sunday, April 6. The resort goes out with a bang, and a busy closing weekend called "Springalicious." The 28th annual Cardboard Classic is April 5, where contraptions are made only with cardboard, duct or masking tape, glue, string, and water-based paint. The secret is Pam cooking spray on the underside of the craft, to make it propel faster down the hill. Steamboat hosts the First Annual Pond Skimming Contest at the base area Sunday April 6. It starts at 3 p.m. to end the season with a big frosty splash. Contestants are judged on distance, crazy outfits, and how much they can get the crowd going. Free concerts also will be at the base area that day, as part of the Bud Light Rocks The Boat Free Concert Series.
