The rock shapes at Brimham in North Yorkshire are both fascinating and unique.
Dating back around 400 million years ago the millstone grit rock formations were formed when what is now North America and Europe collided. Mighty rivers washed loose sand, grit and pebbles down from the mountains and flowed into a delta which is now known as Yorkshire.
As the water slowed down the grit and mud settled on the river beds. The grit included crystals of steel-hard quartz and softer crystals of feldspar. Over millions of years these layers compressed and hardened to form the layers of rock that can be seen today.
