Treasure hunting is a lot of fun, though from experience if you really do find something, it's not always a good thing for the relationships of those involved.
Always have a written agreement prior to starting with anyone involved before starting; that is the search crew, land owners, etc.
Oh yes, we even drew up contracts for how to split it and what to do in case of legal action, death, etc. I think we based it off the one in The Hobbit, but it has been a while. It was fun to read though as I do remember that there was a clause that you had to drink a few beers before negotiations could start. In general, it was enjoyable to go out and do that shindig and I would suggest it to others to have fun with it, but be sure not to, you know, die while out tramping about in the Rockies.
