Rock of the Knox group in the central uplift are raised 250 m (820 ft) above their normal position and locally contain shatter cones. In the rim surrounding the crater, Ordovician limestone has been uplifted 10–50 m (33–164 ft) and is moderately to tightly folded into doubly plunging anticlines and synclines that have axes concentric to the ...
