For the next 9.5 miles (1 5 km) the routeis over the outcrop of St. Louis and Ste.Genevieve (Mississippian) limestones. Theterrain is characterized by numerous sinkholes;surface streams are rare because muchdrainage is diverted to subterranean routes.On right, road to the open-face operation ofFredonia Valley Quarries, Inc.
