Came here with Martin and Norie in late 2000. After walking through the woods past Dumgoyach Hill, we sat and watched the comings and goings of a gardener at Duntreath Castle and the ramblers at the summit of Dumgoyne Hill, through the binoculars. This alignment (of which only one stone remains standing)is set on top of a shallow raise in the green Strathblane, between the Kilpatrick Hills to the west and the Campsies to the east. I didn't feel at all well that day, but typically did not tell anyone.
There are 6 stones closely aligned from SW - NE. One remaines standing at 5 ft.
The archaologist, Andrew Selkirk believed that this was not simply a stone alignment, but that what sits there today are the remains of a long cairn. Aubrey Burl goes along with this theory in his book 'Carnac to Callanish'.
Charcoal was found here and the carbon was dated to 5400-5500 years.
I'm not sure if the charcoal found, indicates that this may well have been a burial site.
Good info and photos. I got much of the info. for my posting from here. Ancient Scotland names this site 'Blanefield', although I've always seen it referred to as 'Dumgoyach'.
