Looking ENE from A, at Mam Tor. Hummocky slipped Mam Tor Beds are in the fore ground. Black rocks to the left are the Edale Shales. Click here to move on to B A

Some years it was possible to repair the road with just a thick layer of tarmac, others fresh mettle was needed! Compares with fault movement generating sediment accommodation space Click here to move on to C B

Looking NNE from D “I’m not driving over that!” – “Why not?” Click here to see ‘Why not’ D

Click here to see the dislocation from further north on the road True amplitude of the dislocation is seen at the ‘stiff’ road, but appears to diminish in the ‘softer’ disturbed bedrock. Might hill-creep have any influence in hiding the fault? Looking SE from D Looking SE from E E
