Using land that connected their two parcels, Otto Wallingford and Dr. Camille Gardner opened Lost Valley Ski Area in 1961, primarily so Wallingford would have something to do in winter-downtime with his family apple orchard. At Lost Valley Wallingford, who had a degree in agricultural engineering, put together the state’s first snowmaking system and introduced Mainers to night skiing. But his biggest contribution to skiing came in 1971 when he started towing a cylindrical steel grate behind a tractor to convert hard snow crust into groomed powder. The Powder Maker became an essential grooming tool and was the signature product of Wallingford’s new company, Valley Engineering, which he sold in 1975.
Lost Valley's variety of 15 trails and a terrain park offers a full and interesting ski day for skiers of all abilities. Most of Lost Valley's trails are rated easiest and intermediate, while challenging expert skiers with a few difficult trails. Family regrouping is simple as all trails come together a short distance from each other.
Lost Valley also offers 15 km (9.3 mi) of Nordic skiing trails and a ski lodge offering food and skiing equipment for sale or rent.
