From an article by David Prudames, published on www.24hourmuseum.org.uk on 21st September 2004:
Experts have voiced their concerns about the future of prehistoric rock carvings on a boulder being used by climbers in the north of England.
Copt Howe, a large rock near the village of Chapel Stile in the Lake District, boasts a series of cup and ring markings believed to have been created between 4,000 and 6,000 years ago.
The site is used by climbers for bouldering, a hard-going, gymnastically-challenging form of climbing without the use of ropes on boulders and short out-crops.
