Man Dry

Mam Tor is a 517 m (1,696 ft) hill near Castleton in the High Peak of Derbyshire, England. Its name means "mother hill", so called because frequent landslips on its eastern face have resulted in a multitude of "mini-hills" beneath it. These landslips, which are caused by unstable lower layers of shale, also give the hill its alternative name of Shivering Mountain.

Great Ridge is a ridge separating the vales of Edale and Castleton in Derbyshire, England. It extends for approximately 3 kilometres (1.9 mi) from Mam Tor at the western end of the ridge to Lose Hill at the eastern end, the lowest point being Hollins Cross.A path runs along the length of the ridge, and is roughly paved to prevent erosion caused by the large number of visitors.

Hollins Cross lies between Mam Tor and Lose Hill on the Great Ridge that separates Castleton and Edale in Derbyshire, England.Hollins Cross is the lowest point on the ridge and is therefore a popular route taken by walkers wishing either to cross from one side to the other, or to start a walk along the ridge.
