Just because the lifts stopped running on April 19th doesn't mean you can't still ski there...you just have to work a bit harder at it. Witt and I decided that we'd try backcountry skiing in what would normally be in-bounds terrain. Unfortunately, the ski area had already plowed the dirt road that leads to the summit, meaning we had to step across dirt (and climb a deep snow cut on the edges) a few times, but otherwise it was still skiable. The strangest part was how deserted everything was...it was like a ghost town! This is the first time I've ever skied at Keystone without worrying about running into someone!
