Other/historical names associated with this locality:
Kohl Ranch; Kohls Ranch; Paleo site; Indian Gardens Paleo Site


A fossil occurrence/site centered about 1.6 km (1 mile) west of Kohl’s Ranch. The site extends along, and a short distance from, the new and old alignments of State Highway 260 from the intersection of Forest Road (FR) 64 in the west to Indian Gardens in the east. The main Kohl’s Ranch site in the center of the area is now buried under a new alignment of Highway 260. A new site, the Indian Gardens Paleo Site, was placed on the Kohl’s Ranch site. It was created and signed with the help of Ben Mohler as an Eagle Scout project.

Primarily a fossil collecting site in limestone and shale of the Middle Pennsylvanian beta member of the Naco Formation. This is one of the most prolific, important and well-studied Pennsylvanian fossil sites in Arizona that has been visited by countless grade school through college students.
