Mike and Annie
Moving from East Nook
towards the west using GPS. Heights and thicknesses are estimated. GPS readings
are from the bottom of the cliff or the slope in front of the cliff.
TA 23373 69168 (East
Nook Point) - Feature in the Chalk - old swallow hole type feature revealed by
recent slump in boulder clay. Solid vertical Chalk cliff
23361
80179
solid chalk cliff - b/c above - this is the edge of
the current full exposure - beyond this is grassed over.
23346 69189 - thin chalk
exposure about grassy sliope, grassy slop above.
Then no exposure until 23338 69192 where there is -
thin chalk exposure about grassy slope, grassy slop above which continues to
23320
69210
Then no exposure to
23314 09209 where the is an exposure above a grassy slope of chalk with fine
chalky gravel above, then coarse chalky gravel then a grassy slope; this
continues to 23301 69224. Two smaller patches of chalky gravels above.
23297 69228 - about 2 m
of no exposure - just grassy slope.
23297 69237 - start of an exposure of fine cross
bedded chalky gravel
with coarse chalky gravel above, at top of
grassy slope. This continues to 23287 69234 where there is only the upper coarse
chalky gravel. Then there is a n exposure of both.
Then at 23284 69251 to
23277 69251 there is only cross bedded fine chalk gravels. And from there to
23289 69267 there is cross bedded fine chalk gravels with coarser chalk gravels
above.
Here is the ravine known as "
Key Hole"
At the other side of this at 23264 69278 the direction
of the bay changes
- here above the grassy slope is cross bedded
fine chalk gravels with coarser chalk gravels above. This continues for a few
metres then there is no more exposure.
At 23220 69285 the
grassy slope gives way to a small grassy slope with a vertical cliff of fine
cross bedded chalky gravels with coarse chalk gravels with a vague cross bedding
above. There are also exposures of coarse chalk gravels about the cliff top (a
raft?), grey looking boulder clay (a raft?) and brown boulder clay at the top.
At 23213 69293 the lower
grassy slope has gone and there is coarse chalk gravels, with a tjin layer of
fine chalk gravels, that has a layer of chalk boulders above it, and then a
thick sequence of coarse chalk gravels that have a vague cross bedding.
This continues to 23198
69281 where there is the start of some grassing over of the middle of the
exposure.
At 23190 69377 there is
a grassy gully above the exposure.
At 23181 69279 the lower part of the exposure is fully
grassed over. And 23177 69277
marks the edge of the upper part of the
exposure.
Then a few exposures
seen in the grassy cliff - some may be slipped:-
23166 69263 - sand
23156 79258 - coarse
chalk gravel overlain by sandy silt
Glacial gravel
Sand
[slumped layered silt
seen on subsequent visit]
23139 69259 calcrete
block
23125 69259 end of
exposure - present valley
23112 69250 drain
23069 69240 left hand
edge of slipway (looking from sea)
then calcrete with sand
and glacial gravel above .in exposure in grassy cliff. The upper part of the
cliff in this western section is boulder clay or grassed over boulder clay.
23080 69233 in situ
chalk, overlain by chalky gravels with cyroturbation at top, and then some more
chalky gravels.(note not chalk gravels but chalky gravels)
this continues to 23071
69233 where there is a slump which extends to 23066 69223
from there - in situ
chalk, large boulders, coarse chalky gravels with cryoturbation at the top
overlain by finer chalky gravels.
Between 23052 69214 and
23040 69208 there are calcrete blocks. Glacial gravels can be seen in the
boulder clay and grass.
From here to 23038 69209
there is a sand layer and then a sandy silt above the chalky gravels.
Between 23038 69209 and
23028 69212 there is another slump. The sandy silt can still be seen though as
can glacial gravels in the b/c and grass above.
From
here to 23016 69221 which is the edge of the solid chalk cliff there is in situ
chalk sloping up toward the left,
with chalky gravels above it, sandy silt, sand
and hen more sandy silt - with b/c and grass above. There is a small amount of
scree like material at the edge of the solid chalk.
