I’ve skied Hidden Valley but I’m looking for an update on the North Arm Trails. Anybody been out and about?

I'm sure folks are attempting it. My guess is that it'll still be a little boney in places- you could take some rock skis, but be careful on the downhills (and getting back to your car will require some serious downhills). Call Camp DuNord for an update (218-365-3681). I left Ely on 12/16 and at that point there was too little snow. My feeling is that you really need a good 18" of snow to allow comfortable skiing on those trails. I speak from experience; I'm certain that I ski those trails more than any other human.
