November sees the Peak District holding its own science festival
- and those who tend to study the area by roaming around it in hiking boots
may discover more about one of its best known hills.
Mam Tor is known as the "shivering mountain" because of the way it is prone to gradual slippage and erosion. While a climb to its summit offers panoramic views towards the Vale of Edale to the north and Castleton to the south, there are many places where the gradual crumbling of the hill is evident.
Visitors to the Moorland Discovery Centre at Longshaw on November 3rd and Bakewell Town Hall on November tenth can learn about how geologists are monitoring the rate at which the slippage is taking place, at an event called Science in the National Park.
The talks will also include explanations of how and why spaghnum moss is being flow in to help restore otherwise barren areas of moorland, something those who have crossed areas of high plateau like Kinder Low may be familiar with as the surface there is a virtual desert.
Walkers may also see plenty of evidence of the 'shimmering' of Mam Tor, with one old road on the Castleton side being closed since the 1970s.
Just beyond where the road now ends, there is a drop of several feet to the next section of cracked tarmac, evidence of just how much the hill has shifted even in living memory.
Walkers crossing Mam Tor may however make it a part of a ridge walk stretching from Lose Hill in the east to Rushup Edge and its wild ponies in the west. Mam Tor itself has traces of an Iron Age hill fort on its summit.
Other scientific topics covered in the event include an archaeological dig at another hill fort - Fin Cop - that uncovered 2,000-year-old skeletons.
