The ever-popular golden arc of Lulworth Cove on Dorset's Jurassic Coast. A Geological and Recreational Wonderland.
Commentary.
A story of rocks, sea, bays for many eons.
Outermost, harder headlands and stacks of Jurassic Portland and Purbeck limestone have resisted the sea’s perpetual pounding.
Where breached, the younger, softer Greensand and Gault Clay has been scoured into a perfect arc.
Waves rolling in on the ubiquitous south-westerly winds
are distorted and condensed in the cove.
In transit, their pattern is distorted within the headlands
to a similar broad curve, further accentuating
the rapid incursions into the softer rocks.
The medium resistance of the Cretaceous Chalk
slows this incursion but where undercut
cliffs collapse, hundreds of tons at a time.
All this geomorphology, geology and
differential erosion is fine, but this place,
first and foremost is a beautiful, sheltered haven,
loved and visited by countless thousands
from within and beyond our magical shores.
