Cleft Rock

Cleft Tor

Set in the Private Land of Ausewell Wood the magnificent Cleft Rock was until 1860 associated with the copper mining industry of Dartmoor. The area is said to be the inspiration for Sir Arthur Conan Doyle's 'Cleft Tor' in his classic 'The Hound of the Baskervilles'. It is certainly an intimidating place that would inspire many a gruesome tale.

Briefly mentioned by Crossing when viewed from opposite, the summit rocks afford tremendous views over Holne Chase to the west and below this point is hidden a fantastic gunnis with a path leading through the cliff face. The walls here are still coated in a dark orange dust reminding the visitor of its mining heritage. The mine was known as both Hazwell and Hazel Mine, according to mindat.org; "Two parallel lodes of iron and copper extend through and alongside the rock and were developed here by open cast working and underground mining. The Cleft Rock itself (which appears is on current Ordnance Survey maps by this name) is a deep gunnis splitting the rock in two. Locally pronounced as 'Azel', the mine, then idle, was advertised for sale as Haswell Mine in 1763 and two years later, in 1765, appears on a map as the Hazel Mine. Workings at this time were from adit and shaft."

Whereas Ausewell Wood could previously be accessed by applying for a walking permit, the woodland has now been sold. The National Trust own most of it and The Woodland Trust are currently raising money to pay a third party who purchased on their behalf. At some point public access will be possible for part of the woods, but whether this will mean the tors here can be accessed in the future remains to be seen.
