As far as I am able to discern, with a map, the reference for the Longpot Head possible stone circle is NY 6682 5055. Please approach it from the Intake/Bertram Hill side - simply diverge from the Public Footpath shown and head for the path that runs up the side of the fell beside the boundary wall. This wall can be clearly seen from the hamlet of Knarsdale and has a cupmarked Boundary Stone (not yet listed) just below, and to the left of, where the script 'Benks Holes' lies.
