I could use a little clarification on one item. It talks about existing routes and trails. The general thought around here is that means marked or designated trails. Are unmarked trails subject to closure? Do they have to have a USFS designation to be valid?
absolutely correct. All unmarked trails will be closed. steamboat, are you a member of thumpertalk.com? This was a big issue on there awhile back. All trails need to be submitted to the USFS and be designated/registered to not be "closed".
