On the broad expanse of Fountains Earth Moor can be found the towering stone stacks of Jenny Twig and her daughter Tib. They stand together, set apart from the neighbouring outcrop of Millstone Grit called Sypeland Crags. Nobody local knows the origin of the names. One writer noted the similarity to the Gaelic 'Tuig', 'to be wise'. In 1863, William Graing rather romantically referred to them as 'Giantesses in broad bonnetts'. It's easy to believe this when you spend any time here. The moorland hereabouts is trackless, remote, scattered with bogs and eerie rock features.
