South Landing July 2006

Fieldwork by Annie Horne, Brian Kneller, Ian Heppenstall, Kelly Wang, Mike Horne and Stuart Jones.

The aim of the fieldwork was to try to measure the cliff face to the 'North' of the Road down into the bay.

 From a distance it is possible to see beds of the "chalk gravels" that dip north to south. There are some layers that are finer than others, and some that contain large chalk boulders. The chalk pieces are all sub-angular in shape. But when you get up closed to the cliff face to try to measure them it becomes difficult to tell them apart as there is often no clear boundary between the beds.

 Here are the measurements around the bay from the roadway going 'north' at the base of the cliff/scree:-

Drainage pipe

Valley

Start of low boulder clay (b/c) cliff

9.5m

calcrete/concrete block

4.2m

slumped b/c

3m

stacked chalk beach pebbles with b/c above [? Raised beach ?]

10.8m

slumped b/c

3m

chalk boulders and pebbles with slumped b/c above

1m

slumped b/c grassed over

15.3 m

thin gully in b/c

start of low chalk boulder cliff

27.5 m of chalk boulder cliff (measured in detail - separately)

slumped b/c with chalk boulder cliff above

5.5m gully

grassed slump

28.2m

approx. position of high level chalk boulder exposure

11m

approx. position of end of high level exposure

gulley

4m

approx. edge of high level chalk gravels exposure

41m

approx. end of exposure

cliff grassed totally

2m

approx. high level exposure above brambles

25m

approx. brambles and grass only

12.5m

approx. start of thin high level chalk boulder exposure

31m

approx. start of solid in situ chalk cliff with scree in front of it.

Vertical cliff sections going 'south' to 'north', measured to base of cliff then to a 'horizontal' line based on a seaweed strand line. We could measure up to about 3.5m from the base of the cliff using a steel tape. The chalk boulder cliff is about 28m high at its highest point with grassed boulder clay above.
