The Lowe-Volk Park Nature Center will be the destination for rock hounds this Saturday. The Park District will hold its annual Rock-n-Fossil Day from 11 a.m. to 2 p.m. at the Nature Center that day.

This year, the Crawford Park District will have a collection of Trilobites on loan from the Ohio History Connection and from local collector Tom Kottyan. The fossils will remain on display for a month.

The Richland Lithic and Lapidary Society will also provide a special exhibit of fluorescent rocks/minerals and the many displays provided by exhibitors.
