Brimham Rocks are natural formations on Brimham Moor in North Yorkshire.
The many different and distinct variations began to take shape millions of years ago, caused by glacial erosion, sand, water and wind.
Owned and maintained by the National Trust, they are part of the Nidderdale Area of Outstanding Natural Beauty.
Since our visit earlier this year, five young people were seen pushing a rock on top of one of the crags. The resulting fall caused irreparable damage and that particular area is now potentially dangerous.
