When we were last there. The mining was real close to the access trail going up to the shooting house. If they have made the turn and headed back with the high wall, then they will (or got) that one trail. The parallel trail up the dry creek bed would become the access.
I have not talked to anyone and DO NOT KNOW. But, lay of the land dictates that as well as me walking through the woods from the access trail to the high wall. After that turn, it would be a long time before they got back to that point again, a couple years I would think.
I will ask Tony next time I see him.
