 Location White Force Waterfall
 Civil Parish Holwick
 Brit. National Grid 
 Altitude 480m
 Geology The Whin Cill intrusion and metamorphosed 'Sugar' limestone.
 Record Name White Force Waterfall, the Whin Cill and underlying metamorphosed 'Sugar' Limestone.
 Record Description White Force is significant as the scene of a visit, on pony with a local guide, by the great pionneering geologist Adam Sedgewick during or before 1827. Adam Sedgwick first to recognised the injected nature of the igneous Whin Cill and that the strata both below and above the Whin Cill had been metamorhosed by contact with the igneous dolerite. (Sedgewick,A.1827. On the association of trap rocks with the mountain limestone formation in High Teesdale, etc. Trans. Cumb. Phil.Soc., 2, 140-196.)

 Additional Notes During periods of low flow, the waterfall disappears into a fissure within the metamorphosed limestone to re-emerge at the base of the falls. During time of flod the Falls are considered to be extremely impressive, rivalling The High Force! To those who know me, burnt stones are not infrequently presented as evidence for the heating of water, however the fragments of Sugar Limestone shown on image No xx were heated by contact with the Dolerite Cill some 300M yrs ago, during the Late Carboniferous. For a detailed discussion on the extent and relative age of the Whin Cill, see Johnson G.A.L. and Dunham 1963. 'The Geology of Moor House- A National Nature Reserve in north east Westmorland.' HMSO.
