Description
Area, 0.7 ha. 1.8 ac. Description This site consists of two of the largest isolated depressions, known as dolines, occurring in the Mendip limestone area and both appear to have been formed by the limestones being dissolved by subterranean waters and the overlying rocks then collapsing into them. They differ in terms of their form and the sediments which partly infill them, Sandpit Role being steep sided with rock walls and containing limestone boulders overlain by dolomite sand, whilst Bishop's Lot is a shallow, saucer shaped depression with a clay infill. Together they are representative examples of the range of doline types which characterise the scenery of the Mendip Hills.
