Abstract: The autochthonous rocks exposed within the Central Champlain Valley range from the Trempealeauian Ticonderoga dolostone through the Middle Ordovician Iberville shale. The sequence is continuous with no apparent interruptions in deposition; possibly a paraconformity exists between the Bridport dolostone and the Chazvan Day Point formation.
