The winter trade route starts at marble mountain snopark in a haze of two-stroke engine fumes and a maze of polaris trailers. Follow the swift creek trail and signs to the worm flows climbing trail. Once at treeline, follow the path of least resistance. Use caution coming down if visiblity is deteriorating. The route is very low-angle, but like the south side of Hood or similar, some decent navigation skills may come into play in low visibility. Gullies all look the same up there. Otherwise, it's a cakewalk for someone with some cascades experience.
