Why this matters
The White Cliffs of Dover are composed primarily of Cretaceous-era chalk, formed around 90 million years ago from the compressed remains of marine microorganisms. The cliffs are notable for their striking white color and vertical faces, which have become an enduring symbol of England and a key geographical landmark facing the Strait of Dover.
What is recorded here
The White Cliffs of Dover are the region of English coastline facing the Strait of Dover and France. The cliff face, which reaches a height of 350 feet (110 m), owes its striking appearance to its composition of chalk accented by streaks of black flint, deposited during the Late Cretaceous.
