Welcome to the Kettle Moraine Geological Society (KMGS) website! The Wisconsin Kettle Moraine area is rich in geological history.

A group of people, mostly rock hounds, founded our non-profit organization in 1960. KMGS is a member of the Midwest Federation of Mineralogical and Geological Society and the American Federation of Geological Societies. We are dedicated to the dissemination of knowledge of the earth sciences, specifically geology and mineralogy. However, our mission has become broader over the years to include teaching and demonstrating all aspects of rock collecting from safety in the field to working with and displaying found specimens. Our members are interested in a wide variety of related areas, such as minerals, gems, crystals, lapidary, jewelry, fluorescence, fossils, and Native American artifacts. We especially enjoy teaching young people how to collect, identify, and display specimens they find.

Informational programs on land formations, gems, minerals, fossils, and artifacts are shared with the community by visiting schools and local groups. We also present programs at our meetings and at our annual Rock, Gem, and Mineral Show, which is our main activity to raise money to fund our educational programs.
