Chris Clemens, President, Midwest Chapter of the Fluorescent Mineral Society

Expect a glowing presentation! Chris will explain the phenomenon of fluorescence, including its cause and why some rocks glow under ultraviolet (UV) light. He will show examples of beautiful fluorescent minerals from around the world, the US and notable locations in the Midwest. Chris will bring a couple of UV lamps with him and briefly discuss new innovations in the UV field lamp technology and resources available to the fluorescent mineral collector. Everyone is invited to bring rocks to the meeting if they'd like and Chris will check them for fluorescence.

President of the Midwest Chapter of the Fluorescent Mineral Society, Chris Clemens is a research scientist by education and profession. His work currently focuses on the use of targeted fluorescent dyes to label and identify cancer biomarkers in malignant cells. Chris has been interested in rocks, minerals and fossils since childhood. His primary interests include fluorescent minerals, mineral photography, the collection of fine minerals from Midwest locations and local geology. Chris moved to Crown Point, Indiana, four years ago after having lived in Utah for 30 years. He is a past president of the Calumet Gem & Mineral Society in Northwestern Indiana.

The Fluorescent Mineral Society is an international organization of professional mineralogists, gemologists, amateur collectors, and others who study and collect fluorescent minerals. Their mission is to bring together people who are interested in fluorescent minerals, and to introduce the public to the hobby of fluorescent mineral collecting.

Geo Juniors are having thier own meetings!

The Geo Juniors are having their own meetings. The kids' meetings are from 6:15 pm to 7:15 pm on the same evenings as our regular meetings, the second Saturday of the month. These budding rockhounds will be learning all about what it take to become one. At the meetings, they will be working on badge work, helping to design and build their website, geojuniors.com, related crafts and a host of other things to help them become the newest generation of rockhounds.


Talk About Digging Things Up!

The club has recently come across old newsletters. We are in the process of digitizing them for posterity's sake. I thought it would be great to post the very first newsletter of our club here for all to see. This newsletter was originally mimeographed (remember the smell of mimeographed pages!) and later zeroxed. With some time and effort, it was scanned in and cleaned up. Click here to see what was going on in the club in October of 1946.
