Scheduling details. <4>

A large and prominent mound. Erosion of the top and sides by animal trampling shows it to be mainly of earth construction although there is no sign of a quarry ditch. The top is fairly flat but there is no evidence of robbing. It lies within two farms. The south-western side has largely been destroyed by the plough cutting into it. The north-eastern side has also been suffering but most of the mound still survives although deteriorating both by animal trampling, plough cutting at the edge and rain washing of the exposed soil. The farmer says the 'there were once standing stones on the west side but these were cleared before the site was protected'. (Smith, 2003)
