Sharonville set aside a hillside of Ordovician shale and limestone more than 440 million years old and simply let people collect it — free, daily, dawn to dusk, no permit required. The slopes shed brachiopods, bryozoans, and horn coral continuously, so an overnight rain does most of the searching for you. Interpretive signs help you name what you are holding, and the trail up the hill pays off with a Cincinnati skyline view.
