01 As discussed elsewhere on the Queensberry, Durisdeer and Steygail and Enterkin Pass web galleries the actual place where the River Clyde first takes it's name and becomes "the Clyde" is a bit of an enigma. In Glasgow for example it was commonly held that the source of the River Clyde was Tinto Hill. There is also a more realistic saying that the Rivers Tweed, Annan and Clyde all rise from the same hill and there is a Clyde Law (OS Ref. NT027171) which is certainly near the sources of the Tweed and Annan Rivers though there is a short descent and ascent in between. Clydes Burn runs west off Clyde Law, runs past a place called Little Clyde and joins the conjoined waters of Daer and Potrail just south of Elvanfoot (OS Ref. NS963155). But I think the odds have got to be very firmly on the place you are looking at in these pictures (OS Ref NS 954137).
Near the left side of the picture above you can see a blue asterisk at the meeting point of the Daer Water (coming from the top right corner of the picture) and the Potrail Water (coming in from the right side of the picture). There is a third "water" running down to meet the other two at their junction, and this is the Glenochar Burn which you see entering the picture from the bottom right corner and passing under the A702 road - which is the other thin band of light running across the picture from right to left and nearer to us. Glenochar farmhouse, among the trees, is at the roadside where the Glenochar Burn runs under it. The red asterisk shows where there is a visitor's car park for visiting Glenchochar Bastle and Fermtoun which of course you could also use to visit the source of the Clyde. To get from there down to the meeting of the waters you walk east along the road past Glenochar farmhouse, over the Glenochar Burn, and in at the gate just beyond it on your right. Check out the map in the Dun Law web gallery for a larger view of the area than is given in the maps below.
So just by the left edge of this picture is where the River Clyde is born though as you can see in the Ordnance Survey maps below there always seems to be an element of doubt - even Ordnance Survey seemed to go along with the idea of Clyde Law being the source as you can see below and for most people the Ordnance Survey is the ultimate arbiter on such matters.
