Eileen- Yes, it's probably worth trying to find a copy of Hanft's Red River book, though the coverage is probably a little heavier on the Anderson & Bella Vista operation than the Round Mountain end, though it does have coverage of both. As for obtaining copies of the book, I see a bunch available on Amazon right now, some new, some used. A large number of copies are also available on Bookfinder, some of them appear to be the same sources and prices as through Amazon. I'm also remembering that the Westwood Museum reprinted the book a couple years ago, though I have not personally seen one of them and don't know if they are still available or not.
