The Berkshires of Massachusetts have long been known as a winter sports paradise. Forty-four ski areas arose from the 1930s to the 1970s. The Thunderbolt Ski Trail put the Berkshires on the map for challenging terrain. Major ski resorts like Brodie Mountain sparked the popularity of night skiing with lighted trails. All-inclusive resorts--like Oak n' Spruce, Eastover and Jug End--brought thousands of new skiers into the sport between the 1940s and 1970s. Over the years, many of these ski areas faded away and are nearly forgotten. Jeremy Davis of the New England/Northeast Lost Ski Areas Project brings these lost locations back to life, chronicling their rich histories and contributions to the ski industry.
