Mam Tor landslip, Derbyshire

Mam Tor landslip, Derbyshire
Remains of the A625 road on the Mam Tor landslip, Derbyshire.

This is a section of the old A625 Sheffield to Chapel-en-le-Frith road at the foot of Mam Tor in the Peak District. The road was built across an extensive active landslip area and was in constant need of repair. The photo shows the repetitive layers of successive repairs made to this section. The road was finally closed in 1979.

The landslip first formed about 3000 years BP, on an oversteepened slope left after Devensian. There is an 80 m high back scar in formed in the Mam Tor Beds.

The toe of the landslip is still active today, moving at up to 2 metres per year in places.

Prime example of where not to build a major road.

Studied this place on a field trip as an undergraduate (BSc in Geography) in the late 1970s
4 years ago.
