Firstly may I point out the Pole Stoop has never been known locally as the Hanging Stone, nor is it marked as such on any maps. It is a boundary stone erected on a once major Keighley to Colne highway. A second stone once stood along the route on the Sutton/Stott Hill, Cowling boundary at Buckstone Lane, this stone, known as Hob Prick Lad, was broken up during the Sutton Inclosure 1815-1825. The cross on the Sutton side of the stone is a cross moline, the heraldic device of the Copley family, once lords of the manor of Sutton. The letter T on the same side, in all likelihood, stands for townend, but may also stand for terminus. On the Keighley side of the stone are the letters WD, which stand for William, Earl of Devonshire. William Cavendish was lord of the manor of Keighley and created Earl of Devonshire in 1618. His manor was surveyed in 1612 and the mark on Pole Stoop was probably made between 1618 and his death in 1628. Pole Stoop was probably erected during the years following the Highways Act 1555, which made parishes and townships responsible for the roads. The word 'pole' is from middle English 'polle' for head and in this case refers to the head of land at the end of the highway and at the boundary.
With regard to the Hanging Stone in Sutton this boulder once stood in the area of Sutton Pinnacle (Lund's Tower). It was lost during quarrying, the long abandoned quarry is still known as Hanging Stone Quarry.
