English: Closeup of a large stone known as "Thor's Stone" or the "Cricklestone" in the marsh by edge of Pudmore Pond, on Thursley Common, Surrey. It is reputed to be an ancient Celtic boundary stone, but may merely be of one of several (possibly late 18th century) boundary marker stones, marking the southern extent of Peper Harow. An outcrop of sandstone to the north-east of Pudmore Pond is thought by some to be the original "Thor's Stone", and it has been suggested that the name of "Thor's Stone" was transferred from the sandstone outcrop to the stone by Pudmore Pond in the late 19th century.
The stone is mentioned by Arthur Conan Doyle in his historical novel Sir Nigel: "He had ridden over Thursley Ridge past the old stone where in days gone by at the place of Thor the wild Saxons worshiped their war-god. Nigel looked at it with a wary eye and spurred Pommers onward as he passed it, for still it was said that wild fires danced round it on the moonless nights, and they who had ears for such things could hear the scream and sob of those whose lives had been ripped from them that the fiend might be honored. Thor's stone, Thor's jumps, Thor's punch-bowl—the whole country-side was one grim monument to the God of Battles, though the pious monks had changed his uncouth name for that of the Devil his father, so that it was the Devil's jumps and the Devil's punch-bowl of which they spoke." (ch.11).
