Following the same line for the
straight section, standing from
6.24.8 into 6.24.7 we find a basin of
limestone with, on average,
dips, the strike in the southerly
portion being read with north dips
and the strike swinging around to
nearly North (N 15°W) and with
east dips of 15 to 30°. These limestones
are cut by 3 dikes of galto. The
northernmost dike illustrates
beautifully folding & siling. The
limestone at this point were
apparently once buried for limestone
as the stratum from old lime hills.
The average strike is N 60° W with
dips of 22° to the N. Not more than
15 ft. of limestones are exposed, the
strike line nearly conforming with the
strike. The limestones are abundant
shrinkage marked and one or two layers
show nummulites.
In the little cove sit the middle
of 6.24.7 occurs a mixture of acid and
basic volcanics, ash 1092, lava 1093,
relations not ascertainable. On the
west side occurs a granite sill.
a couple of feet thick 1094 and in
the limestones, the granites cut by
a basic (galto) dike of
of the same layer rock as 1096, 1093.
There is apparently a fault line as
shales are brought up on the south-
north side of the lake. The shale forms
the west shore of the little cove as far
as the point of the main shore. In this
shore occurs a little cliff of shale
striking N 60° E and dipping only 6° to
the west. The shale dips under a
galbo sill - the sedimentary layer in-
clude is to 15 feet of very flat clay
shales with extremely flattened lay
clearage, in calcareous matter in the
lake. These follow 420 feet of unusual
clay folded shales closely under the
lakes. In the thin shattered lower
shale a single Craticorad (Bayreuths.
large) leaf from a centimetre long was
found, also a single Camellibrual of
Pterines densurus - these slates may
be more fossiliferous but are so stretched
to show any other fossils. The upper
massive upper shales contain several
Bayreuth species and a Trifolium (few
spined) gastropod 6.24.7 B. The lower
shale two fossils are 6.24.7 A - D.

In the cove as the S.W. corner of
sect 3, west of Birch Pt., some faded
sediments appear on the east side these
are green gray calcareous lods
coursely rolled in stone. The beds
strike N 80° W and dip to the north at
a very low angle - 6 to 10° they may
possibly be volcanic flows. They lie to
the south to north of the base of these
of the sand forest of Birch Pt. in 3.
51.7) their sedimentary beds, 1091,
also crops out south side of bar at its
right side.
These beds dip under a
massive trap or fine galbo 1097
which contains a vertical veins of
chunks of pink syenite 1096A
while the same vein if followed
along for 40 or 50 paces as seen to
turn into a green episode or olvin.

Continuing along the shore the rock
1091 is seen to a basin of rather
princesses cleavate shales, the
shale & unloos rock N 34° 2.57° N
and the eastern joint of 2:55. B. At the
outside meets up not in the same.
