In 1904 the Ebensburg & Blacklick Railroad extended its rail line from Dilltown to Blacklick Station. Two different construction companies worked the line from each end to speed up the construction. The large rock formations that you see here, near Heshbon, were blasted out of the hillside by the railroad construction crew.
