That's country where you will want more power than you're used to. Elevation for wolves is gonna eat a big piece of the power you have experienced in Alaska. The good news is there's a groomed trail not terribly far away in those areas to save on the trip in and out.
I'm farther north but similar terrain and 60 miles in our area is a long long day.
I'm not in Alaska, I asked in this sub-forum because Alaskans likely know their stuff about 'winter equipment'.
I have to get a better handle on where the deer/elk [wolf/mountain lion food] migrate to and the terrain there.
