Folsom is a small village in Union County. The town was named after Frances Folsom, the fiancée of President Grover Cleveland. Its claim to fame is the discovery of the Clovis lithics in Wild Horse Arroyo. The Folsom Tradition was a Paleo-Indian time period dating to between 9000 and 8000 BC. The Folsom Site, about 8 miles west of the village, was excavated in 1926, and was found to have been a marsh-side kill site or camp where 23 bison had been killed using distinctive tools, known as Folsom points. A small museum is located there commemorating the event.

After George's death Carl Schwachheim a local blacksmith and amateur "bone hunter" found a fluted spear point imbedded there in a bison rib. In 1926, archaeologist Jesse Figgins from the Denver Museum (now the Denver Museum of Nature and Science) arrived at the site to begin excavations. Figgins discovered a light, fluted projectile point (Folsom point) buried between two of the bison's ribs, thus establishing a clear association of the point with the species of bison that had been extinct for approximately 10,000 years.
