Find this intersection
one road is dirt one is paved choose the right one and head down it
eventually you will come to a downed tree partially blocking the road, I shouldn't still be standing behind it giving doc the bird but you never know.
In case I'm not there here is a less blurry shot that V8 didn't take
go to tree and you will see this, there will be no orange arrow
the arrow is pointing to a piece of bark under the bark is
good luck and happy tagging
