Even at 187 feet (57 m), the towering face
of Whitby’s East Cliff high is no match for the constant bombardment from the treacherous North Sea. The
crumbling cliffs which characterise the rugged Yorkshire Coast have given rise
to shipwrecks, tragic loss of life and even tales of vampires. But those rocks,
which have showered down from the face of the cliff, have revealed secrets held
for 176 million years.

Ancient fossils fall
regularly from the cliff face and fossilized footprints of dinosaurs have been
found on the Whitby and nearby beaches. Stretching
35 miles (56 km) north and south from the mouth of the River Esk, this section
of North Yorkshire’s forbidding coastline has been named the 'Dinosaur', 'Fossil
' or 'Jurassic Coast'.
Recognition of the town’s links
to the Jurassic Era is seen in Whitby’s coat-of-arms. It features three
fossilized ammonites.
Whitby – or - Hwitebi (meaning “White Settlement” in the
ancient Norse language) is located on an area that was once a swamp where “three-toed
carnivorous Theropods and Britain’s oldest plant-eating Sauropod Dinosaurs”
roamed and flourished.
“A dinosaur backbone, which dates back about 176 million years to the
Middle Jurassic period, was found on a beach at Whitby after it fell out of a
cliff face.”
Petrified bones of an ancient and almost complete crocodile have also
been discovered together with many other fossilized specimens.
But in more recent years
(17th to 20th centuries), it is two legacies of the Jurassic era that has helped
Whitby prosper commercially. The most important is Alum – “a product that brought
both wealth and devastation to the Whitby area”.
While alum has various
uses, its prime use in Britain was as a dye-fixer (mordant)
for wool.
The woolen industry was one of England's primary industries – especially in
Yorkshire.
From the late 15th century,
alum had been imported into England from the Middle East
and Papal States. The history of its usage dates back to 1500 BC when the Egyptians
used the coagulant to reduce the cloudiness in water.

With the discovery of alum
shale in the Whitby area in the early 1600s, an industry was founded to process
the shale
and extract the key ingredient, aluminium suphate. Urine was used in processing.
“This was an important
contributor to the Industrial Revolution. One of the oldest
historic sites for the production of alum from shale and human urine
is the Peak Alum Works in Ravenscar, North Yorkshire.
“Unfortunately, however, by
the 18th century, the landscape of north-east Yorkshire had been devastated by
this process, which involved constructing 100 ft (30 m) stacks of burning shale
and fuelling them with firewood continuously for months. The rest of the
production process consisted of quarrying, extraction, steeping of shale ash
with seaweed in urine, boiling, evaporating, crystallization, milling and
loading into sacks for export. Quarrying ate into the cliffs of the area, the
forests were felled for charcoal and the land polluted by sulphuric acid and
ash.”
Jet shop and workshop on Church Street |
Whitby’s second commodity,
dating back to the age of the dinosaurs, is lignite, a black semi-precious stone
that is polished to make pieces of jewellery. It is known as Jet.
Lignite is also found in shale.
It was heavily quarried in the area in Roman and Victorian times, and led to
the development of a thriving local industry that was at its height in the mid-1800s.
Workshops were set up in Whitby to produce ornaments and mourning jewellery. Local boys and women were employed in the
workshops to hand-polish the stones. Black Jet jewellery was made popular by
Queen Victoria on the death of her husband Prince Albert. (See my earlier post)
Today, Jet is still
polished in the town but there is little demand and Whitby’s future economy
will depend on a proposed wind farm (the world’s largest) to be constructed on
the Dogger Bank in the North Sea.
