Fell Beck
Fell Beck is a stream flowing near the foot of Ingleborough, in the West Riding of Yorkshire, amongst the Yorkshire Dales. The stream is notable as it plunges into Gaping Gill, the second-largest natural cave shaft in the United Kingdom (after Titan).[1]
The beck as it falls down the shaft for 360 feet is the tallest unbroken waterfall in the United Kingdom.[2]
The beck later emerges as Clapham Beck in Beck Head Cave. This was proven by fluorescent dye tests many years ago, but only confirmed by cave divers in the 1983.[2]
At times, Fell Beck is blocked off by a temporary dam to allow members of the public to descend the shaft on a winch.[3]
Beyond the village of Clapham, Clapham Beck flows into the River Wenning, a tributary of the River Lune.
