Exploring Earth Sciences Since 1945

Minnesota Mineral Club

We are a non-profit organization devoted to the study of Mineralogy, Geology, Paleontology and the Lapidary Arts.  We are an educational group based in the Twin Cities area of Minnesota, although membership is not restricted to residents of Minnesota.  Monthly meetings are open to everyone.  The Minnesota Mineral Club is a member of the Midwest Federation and the American Federation of Mineralogical Societies.

Field Trips

The club organizes many great field trips throughout the year to places such as Montana, South Dakota, Iowa, Thunder Bay, Michigan, and also places within Minnesota.  We collect agates, geodes, fossils, amethyst, petrified wood, dinosaur bones and other assorted mineral specimens. By all accounts, members have a great time and return with loads of treasures.
