Jupiter River Formation. With progress upward the Gun 
River formation becomes more shaly and this culminates in the 
second zone of the Jupiter River formation which is almost en- 
tirely so, though carrying a small proportion of sand. Following 
the shale zone the sediments become more calcareous. The 
above statements apply only to the western outcrops of the south 
shore. In the eastern outcrops, both the upper Gun River and 
the Jupiter River formations consist of alternating shales and 
limestones. The thickness in the western outcrops is 562 feet, 
that in the eastern is unknown. 
In the western outcrops the ecologic conditions at the time 
of deposition provided a fades favourable for graptolites and tri-
