In looking at the geology and structure of the
region this morning it is evident that the Oolitic
originally extended far to the north. It is now presumed
to down faulting on which the Caledonian mass has
acted. This structure was finally made during the
Taemian Disturbance and the old lines reaccentuated
again in Tertiary or later times.
As we go through St Anne de Beaupre the fault
scarp is more marked. To the south are the pine farms
and to the north the conifer wooded jagged ridge. Far
back of the latter are the Laurentides.
(21 miles from Quebec)
At Chantemerley one rises at once up to the upper
river terrace at 300 feet but farther to the east, this
rise is broken up into a number of smaller terraces.
Some of these are beautifully formed on the farms, little
sharpe ascents of about 50 feet. In other cases it is
all one graded slope to some major terrace beneath
which begins another slope
In places the shales rise higher
upon the Granite ridge.
