I thought of Lambfoot Dub straight away but then I wonderered if it is Middleboot Knotts Tarn?
A stunning picture, Richard - absolutely beautiful!
The banks don't quite look like Lambfoot ( and the water in Lambfoot is quite dirty for some reason )
There was a post similar to this a few years ago where the correct guess(ee) then posted their " where am I " photograph.As it's your post Richard, are you going to keep the photos coming and us lot guessing ?Great photo by the way
