Re: United Verde & Pacific Map - NG *LINK*

The link below provides a map of the original route of the SF through Johnson Canyon. If you want to go explore the old tunnel it is just a few miles west of Williams. I got to it from the west end of the canyon. If you zoom in on the west end you will find a dirt road that generally heads north and intersects the grade. This is where I turned off and drove the grade. As I recall there was one forest service gate to open but that was about it. I drove it in my extended cab 4x with no problem. I have never explored very far east of the tunnel. It looks like the grade goes right by someones home further east.
Be sure to look for Johnson Crater on the road up to the grade. It is on the west side of the road. I'll try to add a marker on the map later.
