Image of Butterdon Hill cairns (Cairn(s)) by thesweetcheat

Another picture showing the upright next to the cairn at SX655586. In this picture, there appears to be the remains of low bank running in a semi-circle and including the upright. Could this be part of a ring cairn or hut circle of some sort, which incorporated the upright?
