The Kettle Moraine Geological Society of Wisconsin (KMGS est. 1961) is a 501(c)(3) non-profit Geology-based organization which invites all to learn about geology and the earth science around us. Member interests include minerals, gems, crystals, lapidary, jewelry, fluorescence, fossils, and Native American artifacts. KMGS holds the Premier Annual Wisconsin Rock, Gem, Mineral and Earth Science Show annually on the second weekend of March at the Washington County Fair Park. Our meetings are held monthly. We teach young people how to collect, identify, and display specimens they find. Our Junior Rockhound Groups meet once a month. We provide Field Trips, Member lectures at schools, Monthly Kids Club Events, Group gatherings, Holiday & special Events appearances, and Class lectures. In 2027, the KMGS will be hosting the Midwest Federation of Mineralogical Societies in conjunction with our March Annual Show.
