Summer Reading Entertainment: Raven Hill Discovery Center’s Cheri Leach will lead readers on an exciting trip through geologic time from the beginnings of our Earth through the ice ages and beyond. Participants will explore the rocks and minerals of Earth and the fossils of the plants and animals that once lived here and collect small rock and fossil samples from “under Michigan” to take home with them. This free event is part of the Summer Reading Program. No registration is necessary. Suggested ages 5-13.
