Sewerby section 13 Oct 2007
Estimated measurements
for a very clear section exposed 2 weeks before.
From left (Bridlington
end) to right (edge of the ancient cliff) -
76 paces - fine chalky gravel, ca 1 m thick at left
and 3m thick at right, cross-bedded
towards left.
21 paces - no exposure
18 paces - sand exposed
behind remains of old pill box (previously exposed)
42 paces - no exposure
19 paces - new exposure
of ca 2m thick chalk beach cobbles, many bored by piddocks, with very few
erratics of yellow quartz; overlain by 1.5 m of sand; overlain by 3m fine chalky
gravels.
2 paces -
no exposure
7 paces - sand (perhaps
with some beach cobbles at base - needs a bit of digging and closer inspection)
23 paces - no exposure
19 paces - sand
12 paces - the classic
buried cliff/raised beach sequence.
(one pace is about 3
feet - but for accuracy compare this with previous measurements from the cliff
to the pill box)
