| Description: | SE side of lake, 300 m. NW of Knight's Grange. View looking north-west across the lake shows a steep bank on the far side which was the original surface of an almost flat area of pasture land. This lake, known locally as 'The Ocean' is the largest of a group of subsidence hollows caused by past brine abstraction in the River Weaver some 2 km. to the north-east. The rather broad area of subsidence is characteristic of sites underlain by boulder clay. Where there are thick sand deposits the effect often has the form of a steep-sided funnel-shaped crater (see also Marton Hole at SJ619674 Photo No. A9406). This photograph is a retake of A9406. |
