A cracking morning on Potter Fell in the foothills of the Lakes north of Kendal. A quiet area largely ignored by those in a hurry to get into the big fells. A dub is a small pond and there were indeed originally three dubs until Richard Fothergill II built a dam to create the much larger lake of just under eight acres we see today. Locally it is known as Fothergill Tarn but the Ordnance Survey refers to it as Gurnal Dubs. The Fothergill made their money came in iron and coal mining in Wales. Their Lowbridge Estate went on the market last year for £3.25m.
