(Meets at the Mason Tract Pathway, Roscommon, Chase Bridge Rd Trail head.) Come join the Michigan Backcountry Ski Series for some of the most beautiful single-track Michigan has to offer. The Mason Tract trail gently rolls alongside the South Branch of the Au Sable River, offering river views, wildlife spectating, and fabulous skiing. The after party will follow at Cross Country Ski Headquarters, where participants can share food, beverages, laughs, and shopping specials.* The after party begins at 2:30 pm. Meet at Chase Bridge at 9:30am, skiing begins at 10:00am. Full tour is a full out and back (approximately 18 miles); however, skiers can ski from Chase Bridge and return to Chase Bridge whenever they would like. Skiers should be self-supported, and keep in mind that due to the tightness of the trail and occasional hills, it is an intermediate-level ski trail. *This event is free; food and beverages are available for purchase.
