On the north side of Ingleborough the series of caves and pots round the little Church of Chapel-en-le-Dale are especially worthy of attention. The chasm at Weathercote opens suddenly in the hill-side, and is perfectly accessible to visitors. You come suddenly upon a cleft a hundred feet deep, with its ledges covered with mosses, ferns, and brambles; at one end a body of water rushes from a cave, and under a great bridge of rock, and falls seventy-five feet, a mass of snow-white foam filling the bottom with spray (Fig. 5). The large masses of rock piled in wild confusion at the bottom, the dark shadows of the overhanging ledges, and the thick covering of green moss, to which the spray clings in tiny glittering drops, form a picture which cannot easily be forgotten. In the sunshine an almost circular rainbow is to be seen from the bottom. The stream passes from the bottom into a cave, and thence downwards to two large pots (Fig. 6), about two hundred yards away. In flood-time the channel has been known to become blocked up, and Weathercote has been filled to the brim. Usually after heavy rains the current is said to flow so violently into the first of the pot-holes, that it throws up stones at least thirty or forty feet from the bottom, with a peculiar rattling noise. From this strange phenomenon it is known as Jingle Pot, while the lower of the two is termed Hurtle Pot, because in flood-time the water whirls so fast round, that it is “hurtled” out at the top. The water flowing through Weathercote is derived from the little stream of Ellerbeck, which disappears in the limestone hills about a mile to the north, and runs at right angles to Dalebeck, or the stream flowing down to Ingleton, which it has been proved to join at a spot below Jingle Pot, by Mr. Metcalfe, who made his way down into it from the chasm of Weathercote.
