Geology at Aughwick Creek

This spot sits on Brallier and Harrell Formations, undivided, mapped as siltstone and shale that formed roughly 385 to 360 million years ago. Sedimentary rock like this erodes unevenly, so the most productive collecting is typically along fresh cuts, badland slopes, and active drainages.
