On Saturday, Aug 11, 2018, a small group of BPS members and guests traveled to Smith County, Mississippi where we were joined by our enthusiastic, knowledgeable host.  We were led to a small working lime quarry that featured, from the Oligocene, outcrops of Bucatunna clay, Glendon formation limestone and Marianna limestone.  The quarry process yielded specimens from the Mint Spring unit but the unit itself was underwater.
