The Iowa Geological Survey (IGS) invites partners, stakeholders, and interested citizens to join us Saturday, September 20, 2025, from 10:00 am - 1:00 pm at the Mediapolis L&W Quarry (17142 Pleasant Grove Drive, Yarmouth, IA) to learn more about our recent mapping project in southeast Iowa.
Geologists from the Iowa Geological Survey (IGS) spent more than six years mapping the surficial and bedrock geology of Des Moines and Lee counties. From glaciers that came from the east (not the north!) to 350-million-year-old rock formations loaded with marine fossils, southeastern Iowa has an amazing geological history! Come to the Mediapolis Quarry for an open house event and talk to the geologists who mapped the region.
Informational booths will be available near the quarry entrance with educational handouts, rock and fossil displays, new geologic maps, and IGS staff to answer your questions. A shuttle will be available to take visitors down into the quarry pit, if they are wearing proper attire* and sign a waiver.
*Long pants and boots (steel-toed boots are preferred). Hard hats and safety vests will be available if needed.
RSVP's are required to participate.
Space is limited! RSVP to reserve your spot.
We hope you can join us! Please feel free to share this event with others who may be interested.
