A meadow-topped hill ringed by a broken stone wall, and one of Ohio's biggest puzzles.

Setting
A mesa-like hill rising about 400 feet above the Paint Creek valley
View
The west side looks over the valley where the Seip and Baum Earthworks lie
Burning
Parts of the wall show signs of intense fire, with slag and glazed rock
Gateways
Openings at the north, on the west wall and at the southeast, where three gates cross a 700-foot isthmus
Access
Free; no improved trails, only an old farm lane up the hill

The story

Spruce Hill is one of at least a dozen hilltop enclosures the Hopewell built in the hilly country of south-central Ohio, and it is the largest. Where most Hopewell works are earth circles and squares on river bottoms, this one is a low stone wall following the rim of a flat-topped hill, enclosing 140 acres that are now a flower-filled meadow. When settlers found such places in the 1800s they took them for fortresses. Squier and Davis wrote that the natural strength of the positions suggested citadels, but more recent work suggests the hilltop enclosures were ceremonial centers, like the geometric works in the valleys.

The wall has a strange feature: along parts of it the stone has been baked. Squier and Davis suggested wooden structures on the walls burned, and the fires left slag and glazed rock. National Park Service archaeologists working in 1995 and 1996 found a ceramic vessel and a flint bladelet at the base of the wall, proof that Hopewell people built it. The site is now preserved by the Arc of Appalachia.

Vikings on the Hill

When the fired stone at Spruce Hill was noticed in the 1800s, people reached for exotic explanations. The hill was once hailed as a place where Celts or Vikings had camped and forged iron, since stone walls with burned patches look like the old fired forts of Scotland and northern Europe. Others said the walls were simply a natural feature.

Nobody has a solid answer for why a hunter-gatherer people built a stone-walled enclosure above Paint Creek 2,000 years ago, or why parts of the wall were burned so hot.

Behind the legend

The Vikings and the Celts have not survived the evidence. The National Park Service's 1995 to 1996 work recovered Hopewell artifacts from beneath the wall, and its own account of the site says the walls probably never resembled a regular laid-up or mortared wall and that a casual visitor might mistake it for natural outcrop. The burning is real, and the hot fires have led to a controversial debate about smelting, but the NPS describes Spruce Hill as a ceremonial hilltop.

Even the trail up has a lesson: the eroded farm lane exposes layers of shale from almost 400 million years ago and rippled sandstone from an ancient sea.

If you go

Climb the old farm lane to the meadow on top and walk to the isthmus, where the stone gates cross the narrow neck. Look west for the view of the Seip and Baum valley. Bring a map, since the wall is easy to miss.
