Caption: Subsidence hollows, Park Sop, Dalton-in-Furness, Cumberland.
Description: The largest drift-covered Carboniferous Limestone outcrops contained masses of haematite preserved in the form of inverted cones. Where these were extracted the resulting subsidence hollows now form lakes. The site of Park Sop is one of the largest of these. The view looking north, shows the ruins of the old mine shafts on the eastern bank, and the Park Limestone is exposed on the eastern side of the lake. The Duddon Estuary and Black Coombe, an inlier of Skiddaw Slates, lie in the distance. Haematite, an iron oxide ore of iron occurs in Cumberland and north-west Lancashire in irregular deposits in the Carboniferous Limestone. In Furness a number of dish-like deposits occupied great hollows in the limestone.
