I would be interested in hunting for this one, I am in Flagstaff. If anyone is interested in getting together for a hunt, let me know and we can get out there and look. I saw a reference to this in Lost Treasure Magazine from 1990.
Have you ever searched out in Rogers Lake? I've made a few trips out there but it is tough because there are signs saying no metal detecting and no treasure hunting. yeah, can you believe it? It actually says "no treasure hunting" on the sign. Going in spring or fall helps though, versus the summer.
