Warren County, Ohio
Forest, Flowers, Falls and Fossils
This 278-acre preserve holds a mature deciduous forest with a large variety of spring wildflowers and ferns. An old field habitat also sustains a variety of species. Halls Creek and Grays Run pass through the preserve, forming small waterfalls as they flow over fossil-rich Ordovician bedrock. Two miles of trails wind through the property between the two creeks.
Protected by Ohio Department of Natural Resources
The ODNR Division of Natural Areas and Preserves operates and maintains the preserve.
