Some additional field notes....
It is possible to access the East Moor area (including Fox Tor and Nine Stones of Altarnun) from the A30 by turning off at Five Lanes and taking the lane to Halvana. After a while you will come to a small group of cottages with a track leading off to a gate on the left. Park here (making sure you are not blocking anybody) and go through the gate and head out onto the moor. Fox Tor towers over you to your left, the east Moor stones and cairns are ahead to the right.
I agree with Pure Joy...finding the stone row from Fox Tor would be nigh on impossible. From this end find what the experts call the blocking stone (see photos) and then head down hill slightly to the right of a line towards Fox Tor summit. After a while you will find the first upright stone...and then another...
By walking in roughly a straight line you will find several more stones, some flat on the ground, some leaning at severe angles, very ocasionally an upright. As you climb the hill towards Fox Tor they become harder to find, you lose sight of the ones behind and eventually end up amongst the clitter of the tor itself.
I wonder...does the row line up with Brown Gelly and the northern end of Dartmoor. I was too busy trying to find the next stone to take much notice...also by the time you get to one end you have lost sight of the other.
I found the North East end of this impossible to find from Fox Tor. I would strongly suggest that if people (without GPS system) want to find it easily they should start from the South West end, which is relatively easy to spot and work backwards.
The only detailed reference I have seen of this row is in Cheryl Straffon’s ‘Earth Mysteries Guide to Bodmin Moor and North Cornwall, including Tintagel’ (Meyn Mamvro Publications - 1993, amended 1995 & 2000) which gives an 8 figure grid ref for the start and end of the row (SX22507815 to 22377785). It says “Between the flanks of Fox Tor and East Moor there is a row of 21 or so stones, with 4 upright and rest recumbent. Another 17 stones or so may be missing, but all are small (about 11/2ft to 41/2 ft) and not very obvious. However at the SSW end, the row seems to be aligned to a more prominent blocking stone set at right angles to the alignment, and thence on to 2 cairns and a possible ritual enclosure.
However I am confused by where the ring cairn and cairn are (as marked on the OS map). If the ring cairn is where the possible blocking stone is, then either the map is wrong or it couldn’t possibly be in line with the stone row (the blocking stone is on the plateau so the rest of the stone row cannot actually be seen from it). The possible blocking stone measures 185 x 105cm and actually looks like two stones together.
I’m not sure what / where the ‘enclosure ‘ marked on the map is (approx SX222779) - I did see a fascinating rectangle with a small ditch around it and no ‘hump’ in the middle nor stones around. Is that it? A very similar site exists between Leskernick Hill and The Beacon on the other side of the A30.
