As we get into the basal beds of the Millstone
Grit at the farthest southern point - about 1/4 miles south
of the gypsum quarry we see again the zones of
nodular limestone conglomerates seen this morning
near Hard Ledge. All of these things go to show that
we are on the opposite side of the anticline seen
this morning by being on the northern limb near Hard
Ledge.
The anticline is evidently a closed one and
with slight slippage goes along the northern side
near the Millstone grit. At the gypsum quarry
the southern dip is again of the regulative dip,
about 20-35 degrees, seen or noted here in the
Cumberland Basin.
Evidently the line between the Joggins series and the
Windon series is true drawn where the brick-red
shales without sandstones and without conglomerates cease.
Joggans division I is not the base of the Joggins series
but far down in Div 8 beneath all of the conglomerates
and nodular limestone a considerable beds. Where
the brick red shales become constant those are the Windon
beds, where they are conglomerates they are of the Joggins
series. The latter always have Pennsylvanian Plants
while the brick red shales have no plants at all.
