I've wheeled Hells Revenge in late January.......shady sides were......interesting. I say go for it and if there's significant snowpack, spend some time exploring less-visited 3-6 rated trails with scenery, like Polar Mesa, Sevenmile Rim and Steelbender. At trip down into Canyonlands Needles District would be an awesome adventure as well, head over Elephant Hill and into Devils Kitchen, hike the Joint Trail with the potential of photographing snow covered slickrock spires in Chestler Park.
