October Mineral of the Month: Celestite

All of the Mineral of the Month selections have come from most recent club fieldtrips, thus far.  If you have a suggestion for a future Mineral of the Month, please e-mail me at:, or tell me at our next meeting.

We are hoping for a possible tie-in to other informative programs that our fellow members might want to collaborate on.
