Kohl Ranch, Tonto National Forest, Arizona, USA
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, State Highway 260, from the intersection of Forest Road (FR) 64 on the west to Kohl’s Ranch in the east. A cut known as the Old Paleo 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 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.
