We’ll walk along Forbidden Drive from Northwestern Ave to Bells Mill Rd and a short distance along the Orange trail. We’ll visit an 18th century quarry and several other interesting rock exposures. We discuss the likely formation of Wissahickon rocks as the result of plate tectonics. This hike is suitable for children over 10 accompanied by a responsible adult.
