The Bouleaux formation is again well exposed along the western side 
of McGinnis cove to the east of the quarry in the Crotalocrinus limestones 
of pointe l’Enfer. The lamination and sun-cracked nature of so much 
of this series, along with the coral breccias, show plainly that the sea at 
this time and place was very shallow, and in fact that the region was at 
times a tidal flat. The descending succession beneath the lowest pink 
limestones of the West Point formation is as follows:

Sandy shales with thin limestones 20 
Limestone, a coral breccia 5 
A jumbled zone in which coral breccias have been tectonically squeezed 
about in the shale, with corals and Crotalocrinus columnals. Strata ver-

shows plainly the shallowness of the sea, since they were virtually 
deposited on the tidal flats of a subsiding coast 32
