A rockfall could kill people walking on the Pennine Way beneath one of Yorkshire's three peaks, according to a man who has climbed the mountain at least 350 times.
Walker and design engineer Gordon Holmes has said a rocky outcrop on the south-east side of Pen-y-Ghent has become unstable and is a "potential danger to walkers", the Westmorland Gazette reports.
Noting that the loose rock is "creeping" by several inches each year, Mr Holmes predicted: "At its present rate it may tumble down the steep slope within the next three years."
But those heading with their backpacks
along the Pennine Way would not be directly affected by a rockfall at this spot, according to the Yorkshire Dales National Park Authority's head of ranger services Alan Hulme.
However, he noted, because the area is open access land he would advise the landowner of the potential danger.
Other mountainous places where loose rocks may cause danger include Lord's Rake on Scafell, England's second highest mountain.
A loose boulder has been lodged there for several years and the route is considered risky.
