This is the best collection of Sarsen stones in the UK. Thousands of stones were left here after the glaciers retreated at the end of the last Ice Age.
To claim a find you need to:
- Explain how these Sarcen Stones were formed (information board at GZ helps, send this answer to me)
- Explain how the Sarcen Stones ended up at the valley bottom where they can be found today (see information board, send this answer to me)
- Take a photo with the Toad Stone and include either your team name or yourself. Attach this photo to your log
Fyfield Down is internationally famous for it’s Sarsen Stones, which are the huge rocks you see at GZ. They were probably formed 30 million years ago. They are the post-glacial remains of a cap of Cenozoic silcrete that once covered much of southern England – a dense, hard rock created from sand bound by a silica cement, making it a kind of silicified sandstone. This cemented sand layer broke up over time due to erosion, and any sand which hadn’t been cemented was washed away leaving the stones behind. Later, they moved to their current position.
Some of the larger stones were probably moved by Neolithic man around 3,500BC to Avebury and now form the huge stone circle and nearby Beckhampton Avenue.
