HAWKEYE, Iowa — The Fayette County Take A Kid Outdoors chapter will have its popular annual "Rocks and Fossils" day from 10 a.m. to 1 p.m. Aug. 24 at Gouldsberg Park in the northwestern part of the county.

Kids will learn about geodes, how fossils were created, the differences between sandstone and limestone, learn how to identify rock formations, and hunt for their own samples in the park’s stream.

This is a free event and families are welcome.

Guest presenters will be Dr. Kata McCarville, an associate professor of geosciences at Upper Iowa University, and Bruce Fink, longtime area rock collector and outdoor enthusiast.

Attendees should dress to get wet and dirty. A light lunch is included.

TAKO-Fayette County is a nonprofit organization dedicated to bringing outdoor experiences to area children and their families.
