deadfall are trees that are dead and have fallen to the ground.
I figured this one out but "Skin up a hill or Skinning" as Snowolf mentioned. This refers to walking or hiking up the hill I'm guessing??
I learn a lot just reading stuff like this. Midwest bunny hills compared to your mountains I would never run into this. But I am wanting to take a trip with my boys at sometime so this is all knowledge shoved into the brain reserves.
I guarantee we are just groom, maybe, tree riders. Still good reads...
