Ancient bison kill site desecrated by mining

When a coal company contractor working under federal oversight used a backhoe to dig up one of the largest known American Indian bison killing grounds and make way for mining, investigators concluded the damage on the Crow Indian Reservation broke federal law and would cost $10 million to repair, according to documents obtained by The Associated Press.

Eight years later, Colorado-based Westmoreland Coal has not made the repairs and is still mining in the area, under an agreement with former Crow leaders that some tribal members said has caused more damage to a site considered hallowed ground.

The U.S. Bureau of Indian Affairs issued a civil violation notice in the case last year, according to agency spokeswoman

Genevieve Giaccardo. A Westmoreland executive said no penalty was involved. No charges were filed by federal prosecutors who investigated potential criminal violations.

Burton Pretty On Top, a 73-year-old tribal adviser and spiritual leader, and other Crow members said they were frustrated that no one had been held accountable for “desecrating” the 2,000-year-old southeastern Montana site. It held countless bison bones and more than 3,300 stone tools and projectile points in an area known as Sarpy Creek.

“It was a shrine or temple to us,” Pretty On Top said.

The mining company plans to repair the damage but has not reached an agreement with the tribe and government on how that should be done, said Westmoreland executive Joe Micheletti.

Crow chairman Alvin “A.J.” Not Afraid said the tribe also bears responsibility, for signing off when Westmoreland first proposed excavating the site a decade ago. The mine generates about $13 million to $15 million annually in revenue for the Crow, which makes up the bulk of the tribe’s budget, Not Afraid said.

The large number of artifacts found suggest that various tribes killed bison there for centuries before the Crow arrived — butchering animals for meat and turning the hides into clothing, according to experts who examined the site. The number of bison bones found makes it the largest kill site of its time ever discovered, said Lawrence Todd, an archaeologist from Colorado State University who participated in the investigation.

The use of a backhoe instead of hand shovels saved the company money but largely destroyed the site, documents and interviews show.
