Good exposures continue from this point to the mouth of the bay. 
This shows not only the upper part of the Enochkin shales but also 
much of the overlying strata. The upper part of the Enochkin 
formation as here exposed is as follows: 
Section of upper purl of EnochJcin formation. 
Feet. 
Dark-drab shale, with numerous bands of limestone concretions filled with 
well-preserved specimens of Cadoceras, Belemnites, etc., and with occa- 
sional sticks of fossilized wood 146

Fossils were collected from the entire thickness of these beds. Dr. 
T. W. Stanton has identified the following forms, which show rela- 
tionship with the Callovian fauna occurring in Europe near the top 
of the middle Jurassic.
