Naco Paleo Site is located approximately 12 miles east of the city of Payson near the turnoff for Kohl’s Ranch and is a popular spot for fossil collection. The site features significant Pennsylvanian Shale-Limestone deposits that collected approximately 300 million years ago, when much of Arizona was submerged 50 feet underwater.

Invertebrate fossil collection is permitted at the site, which is rich with fossils of modern-day fish, reptile, and insect ancestors. A large parking lot area is provided at the site, accommodating standard vehicles, motorhomes, and travel trailers. Visitors should bring their own tools for excavation and should note that vertebrate fossil collection without a permit is strictly prohibited by the Bureau of Land Management.
