GREAT LAKES UNDERGROUND

We have recently come to a crossroads and have made the decision to focus our attention on scuba. We have made many wonderful friends through the rock side and are thankful for all the terrific memories... Great Lakes Underground, located in Midland, Michigan, is Tri-Cities rock, mineral, fossil shop. We offer a variety of specimens, Lortone Lapidary Equipment, and Fisher Metal Detectors. We are also a full service Scuba Shop (Underwater Antics).
