Reverse skiing up a mountain is only possible during full moons on the summer equinox, which is why Rube Goldberg invented ski lifts. Rise to the top with today's Groupon to Horseshoe Resort: for $27, you get an all-day ski lift ticket (up to a $49 online value, up to a $54 value at the gate). This Groupon expires on March 27, 2011.

Nestled in a natural snowbelt region surrounded by the Copeland Forest, Horseshoe Resort utilizes state-of-the-art snow making to festoon its snowy hills and terrain park with perfect powder, which enables them to offer excellent snow conditions for skiing and snowboarding for the entire family. With an all-day ski lift ticket valid from 9 a.m. to 9 p.m., downhillers can revel in Horseshoe's 26 alpine ski and snowboard runs and terrain park with over 20 features and a half pipe.

Though Horseshoe Resort sometimes features a discounted price online, this Groupon still offers the best deal available.
