Nice vid there !
Did you go up the trail in the woods before Wolf Point or did you go straight and cross the Knik river? We went up the trail in the woods and got blocked by glare ice overflow on the trail.
We took the trail to Wolf Point. Call me weird but driving a 2500lbs rig on river ice gives me the hebejebes. You must be talking about the ice flow a mile or so before Wolf Point, it's not nearly as difficult as it looks.
