We visited the stones at Drumtroddan on the 24th Oct 2010 and there is now only one standing. The stone to the west which is seen standing in 'the modern antiquarian' (page 360) is now lying on the ground. It appears to have faillen recently because the soil on the base looks fresh. Interesting that such a small portion appears to have been in the ground!
Getting to the stones proved to be an adventure. I decided not to bother the farmer, and went round to the south. I saw the sign, but managed to miss the stones in their prominent site and turned down a narrow track. 20 minutes later, I breathed a sigh of relief as I arrived back at the sign. Do not go down the track, unless you have a jeep! The walk up to the stones is easy, and well worth the climb. The stones are very tall and stand on a natural platform, with clear views of the Galloway Hills, to the east.I noticed that the stones lined up eith a well defined notch in the distant Hills. Driving back up towards the A75, I tried, but failed, to see this feature from any of the roads' many vantage points. On leaving the fenced in site, I found the field to be full of 'shrooms ( it was September ). If I had got lost later, I could have blamed it on them!
