Flintsteel/Nassau Mine was one of several sites for "Datolite Day"
trips during few of the Keweenaw Weeks. Already, many datolites
have been found. I don't know if any more
datolites can be still found there. This mine is best known for
its bright red datolites with white rims and they have been
found in pink, orange, gray, yellow and possibly lavender colors.
