Checked out a spot I hadn't been back to since moving back. Found several lenses of fossils but the siltstone is so fragile that it crumbles to nothing. There is one layer of harder stone but it is impossible to climb up to. This chunk had tumbled down and gave me my find for the day - a nicely partially weathered out solitary horn coral. Devonian, Brallier Formation from near Roaring Spring PA.
