In Johnny Carrey's book The Middle Fork: A Guide (Backeddy Books, Cambridge, Idaho, 1992), pages 200 - 223 is some of the story of Charles Ernst. Bill Sullivan is also mentioned, as well as is Bill Wilson, my grandfather, who owned the Meyers Cove Ranch, in the Middle Fork.
Charles Ernst died at age 58, in March of 1945.
If you are unable to find this book, email me and I will copy the section on Ernst and mail it to you.
