A local sheriff says artifact hunters are illegally digging where ancient human remains were found this summer.
Barron County Sheriff Chris Fitzgerald says deputies recently found several large holes on county-owned land near the discovery site. He says there are no trespassing signs posted.
Fitzgerald says boaters found the remains at Prairie Lake back in August in a pile of logs or bark and they may be from a Native American burial site.
The sheriff says scientists are still trying to figure out how old those remains are.
