Piles of rock or ancient Indian burial ground?

NORTH SMITHFIELD, R.I. -- In a thick forest of maple, willow and oak trees where 17th century European settlers fought hundreds of American Indians, algae-covered stones are arranged in mysterious piles.

Wilfred Greene, the 70-year-old chief of the Wampanoag Nation's Seaconke Indian tribe, says the stone mounds are part of a massive Indian burial ground, possibly one of the nation's largest, that went unnoticed until a few years ago.

"When I came up here and looked at this, I was overwhelmed," said Greene, a wiry former boxer, standing next to one of at least 100 stone piles -- each about 3 feet (1 meter) high and 4 feet wide...

But Narragansett Improvement Co. disagrees, and says it will press on with plans to build a 122-lot housing project over 200 acres (80-hectares) in the area near the Massachusetts border.

The firm has hired an archeologist who studied the stones and concluded they were likely left in piles by early European settlers who built a network of stone walls in the area, said company president John Everson.

"I don't believe any of these Indian artifacts are on my land," he said. "The whole area is very stony."
