I'm not to sure about where the wagon trail/roads started. I haven't been there lately but I THINK I remember a very large water pipe/well. This is where I remember seeing it. If you go east of the cemetary you come acoss a foundation. Off the northeast corner (I think) I sort of recall a small fence. There was a large hole with some wood around it also, what came across as a old well maybe. I looked down the hole and saw a very large broken iron pipe. I remember the pipe because I though it was rather out of place. I don't know how much this will help. Maybe with a metal detector (which I have) you might be able to find out what direction they go. As a metal detector I know how little information can be a big help. Good luck.
