From the top of Great Rigg the main ridge ploughs on due south, descending over the tops of Heron Pike and Nab Scar and carrying the ever popular Fairfield horseshoe walk. A second shorter ridge descends steadily to the south west over gradually roughening ground, until after three quarters of a mile a rock outcrop is thrust up. This is Arthur's Chair and the ridge upon which it stands is Stone Arthur. Prominence is negligible, and other than the low outcrop itself, the "summit" is merely the point at which the gradient steepens markedly.
