Yordas Cave

[1][5] The shafts are equipped with resin P-hangers allowing the cave to be descended and ascended using standard single rope techniques (SRT).

In flood conditions a lake can rise in the Main Chamber up to 2 metres (6 ft 7 in) deep, before the water is able to flow out of the show cave entrance.

[11] The underground stream next appears in Kingsdale Master Cave, and it resurges at Keld Head 2.7 kilometres (1.7 mi) down the valley.

A number of different false floors which may still be seen clinging to the walls indicate that the cave was subject to cycles of deposition and re-excavation during the recent ice ages.

[15] He described stopping at Thornton at the bottom of the dale "to procure a guide, candle, tinderbox etc", and he also noted inscriptions "above two hundred years old".

Hutton's guide recounted the tale that about fifty years earlier, a pregnant woman travelling alone was taken in labour, and died in the cave.

[9] After the publication of Hutton's description, it became a destination for those seeking the picturesque, and is featured in most later guide books of the area, and is often described in magazines.
