It appears that the cut will affect most of the upper trails, from Airport to Five Mile and Christmas Tree, perhaps as far as Merlin.
The blazes are widespread throughout the upper trail system.
I have no information on what will happen as far as trail access once the timber harvest gets underway. I suspect that access will have to be limited in some manner or curtailed. Hopefully, we'll retain some access during the process and the trails will be OK after the cutting. I'm sure they'll need work after being worked over by logging equipment.
For now, just beware that at some point, there will be some timber cutting at Camp that will likely affect mountain bike access. If anybody knows more about this than I do, please feel free to post a comment!
