Good afternoon Bodi: The map your are referring to was drawn by members of the Dons Club for use on some of there early Dons Treks. It was shown to the people who participated on the "Long Hike" and the "Overnight Hike,more as a gimmick then anything else. The information for drawing the map was derived from a supposed copy given to Oren Arnold, (a member of the Dons Club), by someone who said it was a copy of a map drawn by, and sold by, Julia Thomas. If you have a copy of the book, "Ghost Gold by Oren Arnold," then look at the center pages which hold the pictures of the book and you will see the one Arnold used to help the Dons Club make there map. Hope this answer your questions. Cordially, Gregory E. Davis, President of the Dons Club, and there keeper of the Dons Club Archives.
