The ESCONI Mineral Study Group will meet on Saturday October 4th, 2025 at 7:30 PM in TEC 1038B at College of DuPage in Glen Ellyn. See Directions and Map below.

The program will be on “Calcite”, presented by Mike Litt and Dave Carlson. Calcite has the largest variety of forms of any mineral, and may be the most-collected mineral in the world. Join us as we talk about all things calcite, look at pictures of beautiful examples and examine many impressive specimens in person. If you have your own examples of calcite, please bring them in.

See you there! If you have any questions contact Dave at fossil54@att.net
