The Denali Highway is in excellent shape from Cantwell to Alpine Creek Lodge. We have been grooming it since early November. No bare spots anywhere along the way. Some easy bumps here and there, but since we've been pulling the drag regularly, they are fairly smooth. Off trail riding is excellent now. 4 to 8 feet of snow in spots. East of Alpine Creek Lodge, very few people have been over there, but those that have say it's deep deep snow starting at MP 62 or so.
Hope to see you out here!
