GRETA, "the rocky water," in the west riding of Yorkshire, and county of Lancaster, is a tributary of the Lune. It rises on the slope of the vast height of the Whernside, and flows along Chapeldale, a very remarkable valley bordered on one side by the towering elevation of Ingleborough, and on the other by the Ingleton Fells. In this secluded dale is Wethercoat Cave, one of the most astonishing natural curiosities in the kingdom—a waterfall of great depth and force, completely subterranean, yet enlightened by the sun which sometimes forms a beautiful rainbow in the spray. The scenery at the village of Ingleton at the lower end of Chapeldale is truly magnificent, especially when viewed from the Burton Road. Here the roaring torrent is seen rushing through the deep chasm, the village church and tower rising far above on its brink, and Ingleborough rising immediately as from a base nearly to the distance of five miles. Here the Greta is joined by the stream of Kingsdale, a lonely glen between Ingleton Fells and the Ridge of Graygrath. In this moorland valley are the cavern of Yordas and the waterfall of Thornton Force. From Ingleton the Greta flows on to Black-Burton, and soon enters Lancashire, and terminates its rapid career in the broad channel of the Lune.
