I have a digital and a paper copy of a mining map of the North half of Stevens County in 1900.  There is a lot of historical information on it about what the names of claims are, where they are and who owned them at the time.  The downside is that the computer file is huge, 288 megs for the “small” version, and the paper copy is so much smaller than the original that you need a magnifying glass to read it.    It is too big to load on and off the website.  If you want a copy, contact me: Joe.Barreca@gmail.com
