The large quantity of bones were the remains of a Native American kill site, Mather believed, where people had killed and processed the bison for food, tools and weaponry.
No skulls were found at the dive site either. Bison brains were used to tan hides.
Mather explained a kill site generally would not contain human artifacts.
“The bones, themselves, are the artifacts,” he said.
