I found one datolite nodule while looking for the rare
agates with copper inclusions in August 2005, and I came back to the same
place and found more in August 2006. As of August 2007, I did some digging
in an attempt to locate the source of datolites out of hope that I might
find larger datolites, and all I found are 15 tiny datolites.. All
datolites found at the Wolverine Mine are very enriched in copper.
