Eden and Scottsbluff points and Cody knives were found in situ in a sand deposit with an estimated geological age of 10,000 to 7000 years. Numerous other Cody complex artifacts from the surface of the site are described. Fragmentary remains of a mammoth in a marl bed are stratigraphically older than the Cody artifacts.
