The Maryland Geological Society is a non-profit organization dedicated to the collection, study, and display of all aspects of the geological sciences. Members include amateur and professional fossil and mineral collectors. Membership is open to all.

The club meets at the Community Center in Bowie, Maryland, on the third Sunday of every other month, beginning in January. Visitors are welcome!

What's Hot

  • 14th Annual MGS Auction on Sunday, September 18! Come help the club raise money and make some yourself. This event always features superb items up for auction. More information and auction forms can be downloaded here.

  • A large mineral specimen featuring emerald crystals has gone missing from the James Madison University collection. Dr. Lance Kearns is asking for our help in locating this specimen in case someone attempts to sell or trade it. More information and a picture of the missing specimen can be found here.

  • At the July meeting, junior MGS members Brooke and David were notified that their articles appearing in the MGS newsletter The Rostrum were among the top 10 junior articles in the American Federation of Mineralogical Societies' national competition for club newsletters. Brooke and David are shown below with Rostrum editor Rick Smith receiving cards signalling this important achievement. Final awards will be made shortly by the AFMS.

    Brooke also received two badges from the Future Rockhounds of America program and presented a PowerPoint presentation on the Lapidary Arts to club members. Check out all of this on the Future Rockhounds of America page.

  • Trilobites invade July meeting. Eric Seifter brought many trilobite fossils from his collection and discussed these extinct arthropods in a "Fossil of the Meeting" presentation. Some of these fossils are shown below and in the website's Gallery.
