Peep this... I got as far west as I could before I had to turn around... I did have to hop across a stream on some rocks/logs close to where I turned back...
This is the farthest I've figured out how to go.

I've gone from the pond to Dan's starting point, and it was well marked/paved.
I keep looking at the link into hacklebarney too.
