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: kencasey98@yahoo.com, 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. |
