South Landing fieldwork October 2009

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.
