Geology at Ashland Mill

This spot sits on Newark Supergroup; Conglomerate, mixed clasts, mapped as conglomerate that formed roughly 250 to 200 million years ago. Sedimentary rock like this erodes unevenly, so the most productive collecting is typically along fresh cuts, badland slopes, and active drainages.
