The Devil's Jumps are a series of three small hills near the village of Churt in the county of Surrey in southern England.
Middle Devil's Jump has an elevation of 328 feet (100 m) and once supported an observatory built by 19th century British astronomer Richard Christopher Carrington.
The hills are outcrops of an ironstone variety of sandstone of the Folkestone Beds of Lower Greensand set among acidic heathland.
[4] The three hills are formed of an ironstone known locally as carstone, marginally distinct from Bargate stone, strongly cemented with iron making it resistant to erosion by the elements.
[7] Of the hills he says: At Churt I had, upon my left, three hills out upon the common, called the Devil's Jumps...in the shape of three rather squat sugar-loaves, along in a line upon this heath...[with] a rock-stone upon the top of one of them as big as a Church tower...The Devil's Jumps are linked to a variety of local landmarks by folklore, including Mother Ludlam's Cave near the ruins of Waverley Abbey, the Devil's Punch Bowl at Hindhead, the village of Thursley and the parish church at Frensham.
