In his book 'Dartmoor Sun', Jack Walker writes:
"Note: For some unknown reason the monuments on Hingston Hill are commonly referred to as being on Down Tor, which is quite wrong. Down Tor is the distinctive tor 700 metres west of Hingston Tor. On the Ordnance Survey, Outdoor Leisure 28, Dartmoor map, Hingston Tor is not identified, but the height of the tor is marked on the map as '372' metres and the stone row is shown clearly. Hingston Hill is the broad whale-backed ridge on which the row and circle lie. Hingston Tor (SX586692) is the rock at the highest point of Hingston Hill."
On the dust-jacket of the book we read: [quoting part of author description]
"Using his skills as a scientist and engineer, Jack set about proving to himself that prehistoric man's knowledge of the universe was fundamental to his way of life."
So Jack is obviously a man who likes to get his facts right!
Publishers are Halsgrove, and it is in the 'Halsgrove Discover Series' - my copy, 2005.
(Andy, I'm sure you'd sell some of these to folk who are interested in Dartmoor, and/or want a straightforward explanation of the calendrical aspect of stone circles and rows. Also the Jeremy Butler series of 'Dartmoor Atlas of Antiquities' are almost essential to understanding and exploring the Moor.)
Something is not right. This message is just to keep things from messing up down the road
