The story

On a high, flat plateau above the Cuyahoga River in Sagamore Hills, Late Woodland people raised low earthen walls to set the hilltop apart. The National Park Service says the place was used roughly 800 to 1,600 years ago. Charles Whittlesey recorded it in 1847, one of two ancient forts he documented in the valley, and within about 20 years plowing had badly worn the walls.

Excavations found large earth ovens and a few briefly used hearths, and in 1983 a ramp of stone, but no houses. Archaeologists therefore read it as a place where people came together for ceremonies and feasts rather than a fort or a village. The people who used it lived in villages with cornfields on the river bottoms below. Today the Old Carriage Trail runs straight through the site, with an NPS wayside exhibit.

Ovens on the Hilltop

The walls looked like a fort to Whittlesey in 1847. When archaeologists dug, they found no houses and no weapons, just big earth ovens where people had cooked for a crowd.

It was a place to gather, not to hide.

Behind the legend

Whittlesey's 1847 record, the dates and the excavation finds come from the National Park Service. The ceremonial reading is the archaeologists' interpretation of what was and was not found.

If you go

Park at the Red Lock Trailhead, walk north on the Towpath to the Old Carriage Trail and find the wayside exhibit. Look for the low ridges in the woods.
