Thanks for the map Dave! Our new RR we are taking over is the original Arizona & New Mexico that hsows in the map. I haven't taken the time to dig out Myrick's RR of AZ that covers the area. The A&NM's original builder as the Lordsburg & Clifton. They built 3-foot gauge from Lordsburg to Guthrie to connect with the Morenci Southern. which later standard guaged and extended into Clifton. Today's MOrenci Industrial RR uses the lower portion of the Shannon Arizona RR to reach our yard in Clifton.
The map show the A&NM tunnels were in some places punched through ridges to replace sharper curves and cuts. This was still obivious.
Cool...
