Gospel Hump

Gospel Hump Wilderness

I am looking into hunting the high country of the Gospel Hump next fall. Was wondering when the access roads to the North and Northwest typically get too much snow for vehicles. I notice the trailheads are fairly high up and the season is late enough there may very well be some snow. Wouldn't want to plan on access and find out its snowed in come hunting season. I do plan on finding some low elevation back ups. Getting the Archery/Muzzleloader tag rather than the Any Weapon tag might be a better choice. Is there winter range in unit 14? The late muzzleloader sounds interesting.
