While the site was used primarily to hunt and butcher bison antiquus, there is evidence that the Paleo-Indians also gathered plants and seeds for food about 7,000 to 7,500 BC.

[1] The site is located on a South Platte River terrace in northeastern Colorado, 9 miles (14 km) east of Greeley near the town of Kersey.

At the end of the summer period the land became drier, food was not as abundant, and they became extinct.

People adapted by hunting smaller mammals and gathering wild plants to supplement their diet.

The tools, dated between about 6,000 and 8,000 BC, include Cody knives and Scottsbluff and diamond shaped Eden projectile points.
