What Makes Happisburgh Cliffs Special?
Happisburgh Cliffs are truly unique. They show us layers of rock and soil left behind by ancient ice ages. These layers are called glacial deposits. It's like looking at a history book written in the ground!
A Window into the Ice Ages
The cliffs display three different layers from very old ice ages. The oldest layer is from about 1.9 million years ago. This time is called the Pre-Pastonian Stage. Imagine how long ago that was!
Another layer comes from the Beestonian period. The newest layers are called the Cromer Tills. These were formed during the Anglian stage, about 450,000 years ago. The Anglian stage was the coldest ice age of the Pleistocene era. During this time, huge sheets of ice covered much of the land.
Scientists can learn a lot by studying these layers. They help us understand how the Earth's climate has changed over millions of years. It's like finding clues about giant glaciers that once covered this area.
