Quebec July 14-1913. Ruth Lewis.
It rained off and on throughout the day but
not enough to wet through. After breakfast on the
train started to see the gully at 8.30.
About one mile to see
the first part of the nine, the red and green shales of the Gully. In one place
there was a thick zone, 10 feet, of conglomerate sandstone.
The red shales are more dominant. In the green
part found the Ostella pretiosa, but Raymond
tells me that this species also occurs in the red shale.
There are practically no fossils in the Gully for the O.
pretiosa is rare. Raymond says that some gastropods
have been found but he has not seen any and does
he know where they are.
Logan thinks the Gully overlies the Lewis shales
but it is now the opinion that they underlay the
former. Raymond thinks the two series are separated
by a fault but to me it seemed like a complete
transition from one to the other. The supposed unconformities are to me nothing more than twistings
in the strata.
