Annual Rock Swap at Missouri Mines State Historic Site June 10-12

The public will have the opportunity to buy, sell, swap or just admire rocks, minerals and fossils at the Missouri Mines Rock Swap at Missouri Mines State Historic Site in Park Hills.  The event will be held from 9 a.m. - 6 p.m. on Friday and Saturday and from 9:00 a.m. - 4:00 p.m. on Sunday on June 10-12 at the historic site. 

This event will bring together rock hobbyists from across the Midwest and beyond.  Participants will be selling, swapping or buying mineral specimens, fossils, rock jewelry and other rock-related items.  There is no charge to attend.

Also during the three-day event, there will be free admission to the historic site museum, which interprets Missouri’s mining history and displays restored old mining machinery and an outstanding mineral collection. 

The event is co-sponsored by the Mineral Area Gem and Mineral Society and the Greater St. Louis Association of Earth Science Clubs.
