Scaynes Hill is a special place in East Sussex, England. It's known as a Site of Special Scientific Interest (SSSI) because of its amazing geology. This means it's protected by law due to its important natural features.
Scaynes Hill covers a small area, about 0.04 hectares. That's roughly the size of half a football field! It was officially recognized as an SSSI in 1999.

What is a Site of Special Scientific Interest?
A Site of Special Scientific Interest, or SSSI, is an area that has special plants, animals, or geological features. The government protects these places to make sure they stay healthy and safe for future generations.
Scaynes Hill is important for its geology. Geologists study rocks and how the Earth has changed over millions of years. This site helps them understand ancient environments.
The Rocks of Scaynes Hill
At Scaynes Hill, you can see yellow sandstone rocks. These rocks are part of something called the Tunbridge Wells Sand Formation. Specifically, they belong to a layer known as the Grinstead Clay.
How Old Are These Rocks?
These rocks are incredibly old! They formed during a time called the Valanginian stage. This was about 135 million years ago, long before dinosaurs disappeared. Imagine how much the Earth has changed since then!
How the Sandstone Formed
The sandstone at Scaynes Hill tells a story about an ancient river. Millions of years ago, this area was home to a large, slow-moving river. This river "meandered," meaning it curved and twisted like a snake.
As the river flowed, it carried tiny pieces of sand and mud. When the river slowed down, these sediments settled at the bottom. Over millions of years, these layers of sand were pressed together. They eventually turned into the solid sandstone we see today.
Why is Scaynes Hill Important to Geologists?
Scaynes Hill is a special place for geologists because it's a "disused quarry and road section." This means there was once a quarry here where rocks were dug out. Also, a road was built through the area.
These activities exposed the rock layers. It's like cutting a slice out of a cake to see all the different layers inside. Geologists can easily study these exposed rocks. They learn about the ancient river, the climate, and the landscape from 135 million years ago.
The site is also part of the Geological Conservation Review. This is a program that identifies and protects the most important geological sites in Great Britain. It helps scientists understand Earth's history better.
