The limestone pavement on the surface of the Cove is deeply fissured and fretted by a pattern of channels. Chemical weathering due to the slightly acidic rain dissolves and widens the many joints of the limestone.

Malham Cove
80 metres high and 300 metres wide, Malham Cove is a curved crag of carboniferous limestone formed after the last ice age. Meltwater, mostly from Malham Tarn, cut back the cove as it fell over the edge as a waterfall. erosion was more active at the lip of the fall rather than at the sides, hence the curved shape.
