Slate Run Metro Park isn’t resting on slate rock — settlers mistook the dark soil for 350-million year old slate. It’s actually shale, a soft rock made from clay deposited by water about 350 million years ago. Slate Run features a variety of habitats ranging from the open areas of grasslands, wetlands and meadows to the forested areas of beech, oak, hickory and sugar maple. Red-winged black birds, meadowlarks, indigo bunting, belted kingfishers and numerous other birds and wildlife can be seen at the 156-acre wetlands. More than 70 species of birds have been spotted. The park features Slate Run Living Historical Farm where visitors can learn about and help with chores on a working 1880s farm. Almost 13 miles of trails wind through the fields, forests, ravines and grasslands. Visitors will cross a restored 1800s covered bridge on one of the trails.
