Re: Malham Cove Waterfall 6 December, 2015
Reading the media reports of the amazing sight of water flowing over Malham Cove, it was evident that records of the last time this happened are somewhat unclear. In fact the BBC report stated that the Yorkshire Dales National Park said it was "struggling to find out the last time it flowed as a waterfall".
Regarding historical records of waterfall activity at Malham Cove, Arthur Raistrick in his 1947 book Malham and Malham Moor (Dalesman Publishing Company, Clapham, Yorkshire) writes:
"Howson, writing in 1850, says of the Cove that "twice within the last forty years the swollen waters of the Tarn have made their way over the Cove, but the torrent was dispersed in one vast cloud of spray before it reached the bottom; its density and the magnificence of the sight may be imagined from the fact that the spectators could not approach within a hundred yards of the foot of the rock without being drenched through". Seventy-five years earlier Hurtley says, "From the Apex of the Cove, after what is in this part of the country called a Rugg, or a succession of rainy and tempestuous weather, when the Water-sink at the Southern extremity of the Tarn is unable to receive the overflux of the lake, there falls a large and heavy torrent, making a more grand and magnificent Cascade than imagination can form an idea of"."
