On Saturday, while many Belfast residents were hauling the week’s corrugated cardboard to the transfer station, a dozen local youth, mostly members of local scout troops, were putting their repurposed boxes to use as sleds.

The Belfast Parks and Recreation Department sponsored the Cardboard Sled Challenge in part to celebrate the recent reopening of the city ski area, located off City Point Road.

The event was billed as a competition, and teams ranging in size from one to five members zipped, skidded, rolled, pushed and crawled their way down a rough 50-yard slope, usually, but not always, crossing the finish line at the base of the hill. Volunteers timed the runs with stopwatches and lined the course, ready to give a helping heave-ho to sleds that stuck in the snow, but beyond the trappings of competition — awards were given for fastest time and the most creative design — keeping score took a back seat to having fun.

Parks Director Jim Bell summed up the competition. “I think everybody who came won today,” he said.

After the cardboard sled races, teens took to the slope on snowboards, while younger children broke out conventional sleds.

At the height of its use in the late 1960s and early 1970s the city ski area, known as “El Depot,” was the site of regular ski races and jumping competitions. Last fall, volunteers cleared three trails that had become overgrown after years of disuse.
