Rock Swap, Oct. 8, at the Gillespie Museum

On Oct. 8, 11 a.m.-4 p.m., bring a treasure from the natural world — rock, leaf, flower, twig — and we’ll trade with you for a small mineral specimen from our museum shop. We’ll be on the front porch.

Bring a mask and browse our new exhibits, “Meteorites/Rocks from Space” and Cindy Leung’s “On the Road.” Cultural credit is available for “Two Exhibits,” “Pollination: The Art of Citizen Science” and “Heat/Work: Two Exhibits at the Gillespie Museum.”

The Gillespie Museum, Stetson’s earth science museum, is at 234 E. Michigan Ave.
