A HELICOPTER is at work over Ingleborough this week, helping rescue three quarters of a mile of the famous Three Peaks walk - by replacing wood with stone.
The path on the western flanks of the fell is at present covered with wooden boards after years of erosion from hikers' boots. But the wood is also in need of replacement and, this time, 260 tonnes of long-lasting stone flags are being used.
Although very expensive, the use of a helicopter is the cheapest and fastest method of transporting such heavy cargoes to such a remote spot - and prevents the damage caused by wheeled vehicles.
The £75,000 costs are being met by the Yorkshire Dales National Park, English Nature and the Heritage Lottery Fund through the Yorkshire Dales Millennium Trust.
Peter Corkhill, English Nature's reserve manager for Ingleborough, said: "This is a vital project in the heart of the Ingleborough National Nature Reserve, which is internationally renowned for its wildlife and the geology of its limestone pavement.
"By providing a flagged footpath the area's many visitors will be able to enjoy the great landscape safe in the knowledge that they will not be damaging the fragile bog in this area."
