We Are Getting Ready For Our
69th Annual Silent Auction

Join us on Saturday, March 10, 2018 from 6PM to 9 PM
for an evening of fun, food and great deals.

Click here for the latest information on our 69th annual auction.

This auction is going to be one of our best!

We have acquired the collection of Robert and Elinor Patterson. The Patterson's traveled across the U.S. in their camper collecting rocks. Upon returning home, they cut and slabbed their finds to reveal their true colors. At the auction you can expect to find old rough, cutting material and slabs. Some of the collection actually has the day they were collected on, dates range from the early 50's through the late 60's. Robert had an ingenious way to cut slabs from smaller geodes and agates. Be sure to check it out or perhaps go home with a "brick". There will be a huge selection of agates, beautiful plumes, many types of lace, Lake Superior specimens and fire agates. A large selection of thunder eggs, petrified woods and obsidian will also be available along with many other types of specimens. The collection was donated by their grandson, Jeff. He wanted to be sure the collection went to people who would enjoy it as much as his grandparents' did. This is an old collection that is not to be missed.

Club members are to start filling out their forms
for the auction and bring them to our next meeting.

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. They share knowledge and experience in collecting, identifying, and displaying minerals which exhibit various forms of luminescence including fluorescence, phosphorescence, triboluminescence, and thermoluminescence.

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.

Did you miss our February 2017 meeting?

At our February 2017 meeting, our very own geologist, Ben Chorn, talked to us about Montana Agates. If you missed the meeting, like so many others who decided the warmth of Arizona and the Tucson Show were calling, you are in luck! Ben taped his presentation just for you. See it here or on YouTube. He has also inspired me to add a new page to the website under "References" called "Video Presentations". Get the popcorn ready & enjoy the show!!
