Hello,

The wery large fallen blocks are I think in the C6 C7 C8 range of
beds. Depending on how much as been washed away since I last visited.
I certainly recognised some C7 beds and collected samples from there.

The fault just to the south of these brings down C3 beds. There is
often a mudflow coming down the gap where the fault line is. The C3
beds look very much like the C8 and C9 ones on the other side of the
fault and unless you know you can mistake them.

The B beds start beyone the C3 cliff face in the muddy slumpy area.

As a Hull graduate you should have reading and probably borrowing
rights to the Library. Though some of the geology books were 'removed'
a couple of years ago and Hull Geological Society has some of them in
a private library for members.

regards, Mike.
