A bison scapula (shoulder blade) hoe found in 2018, provides evidence of horticultural activities in the area, Malainey said. The bison scapula was mounted on a shaft and used for gardening, "The same way you have a garden hoe."
At the top of the site is a horticultural area. Items found indicate farmers arrived there around the late 1400s to the early 1500s. They were there until the late 1700s to early 1800s.
