Said to have been given the name by Harry Starkey, references to the area also appear in High Dartmoor where Eric Hemery describes Knattaborough first as 'a rounded tump of rock on the watershed' and then as a 'conspicuous feature not mentioned by Crossing'.
Tim Jenkinson (1996) later includes Knattaborough as a lesser known tor describing the rocks as 'disappointingly low' and goes on to explain that 'the largest segment of the ruined tor sits above a track that runs through the outcrops en route to Oke Tor and Hangingstone Hill beyond.'
He continues 'North-east of the grassy summit the remains of a second elongated pile that has spawned a large clitter, overlook the River Taw to the east. Several partly worked and rounded stones can be found abandoned on the tor's slopes.' Despite this somewhat lukewarm impression of the area the high point of Knattaborough proves an excellent spot from which to enjoy the dramatic ruggedness of both Taw and Okement country. In addition to the rocks on offer, there are no less than four abandoned millstones on the western slopes that were noted by Steve Granger as recently as 2019. The pair shown below can be found at SX 61019 90960 and are indicative of the stone cutting that one took place in the vicinity.
