Spruce Hill is a small sliver of Ohio's geologic library, rich with a beautiful biodiversity, and laden with evidence of the prehistoric Hopewell culture. Even the trail that leads up to the storied plateau area contains geologic "windows" that allow us to see back in time. The sediment-washed trail has countless exposed layers of shale which date to almost 400 million years ago. Rippled sandstone, which dots the trail, is direct evidence that the area was once under the cover of a sprawling ancient sea. The lush woodland hillsides nurture rare and exotic flora and lively fauna of all shapes and sizes.
Spruce Hill Earthworks is not open for daily visitation. However, you can obtain a pass to enter the gated parking lot to take a moderately strenuous hike to the top of the hill.
