Block form seams containing all exposures lenticular
seams full of Operculites at "28" off," appear to follow
an exposure of minor contact on the strike, and large clumps
of tuff are included in the base of the "tuffs" as met.
See thin splintering shales, near in the extreme
corner of the one in the left hand side striking N.15°W and
the strike running around to N. 30°W on the course of 20 paces
northward, between them, crossing the road at the
bridge we find the little creek to run nearly along
the line of outcrop of the Shales which are exposed
striking N.40°W and dipping 15° N.E.
On the east side of the E boundary of 1957-9 and
5E boundary of 1956 shales appear striking N.58°W and
dipping N.70°L at a low angle. The Shales appear on
the northerly side of this line displaying few
fossil indications and are overlain by the tuff.
Fossils seen in several seams in the shales and valves
Chonetes (common), Camarotoechia (common), Tentaculites, Thelodus,
Reyrichia, Actinoptarella, Grammysa sinuata? Mucrites, ?Horismen
danbyi, Crinoid sps., Heliosiphon sp. = 1956 A
These shales are overlain by a granular tuff breccia
(whole aluminous of pfeppar). Immediately under the
tuff where the Shales are naturally crumpled and
rolled and a few traces of baste appear to be included
at the base of the tuff breccia: very few abulite
fragments are included in the lower half which
quite the rock the appearance of the grained tuff
shale geography. In the upper tuff, especially the
upper foot there at some stratification
the beds strike N 35°W and dip 26° N.E. the
strike from these beds up to a slight deflection where
the hill is replaced to the S.W. with thin feet of Shale
perfectly laminated Chonetes seem now to be absent as met
south, Thelodus, Reyrichia. = 1956 B (not collected)
The shales here strike N. 35°W and dip 27° E.
There is another found alone extending N. 27°E
and bringing the tuff. Shale there appear in
running to the deflection indicated within a small depth
apparently fault extends N.E. The hills are
steep sided S.W. inland as well as at slope so that
it is fairly certain also the displacement of the
clear side makes it, hard to

about 175 ft from the Seymourapam Road. Fossils
found in these shales = 1959 A.

dipping south of East, and continuing
Linguula (large, fairly striate, common = ? rare

be seen; found in glass)

Perhaps 5 feet of shales "are exposed at this point?
