Gordale Scar Tufa Waterfall. The sheer limestone cliffs are impressive at this locality. Many inspired discussions have taken place on the merits of "Collapsed Cavern" or "Sub - Glacial Channel" as a mechanism for gorge formation. The source of the water for Gordale Beck is Malham Tarn. The tufa waterfall is often traversed by ramblers (and geologists') and as such has suffered considerable erosion.
The Cove Limestone Member is the lowest limestone unit in the gorge. It is characterised by a distinctive 'platy appearance' typical of Holkerian limestones in this part of the Yorkshire Dales.
