HER no. 8219 (SO 2764 5959)
Here the dyke comes around Herrock Hill and bears towards the east in a roughly west-east direction. By the Old Quarry its scale gradually increases as the slope is less steep. It is a bank with lower berm and upper spoil trench. On the saddle by spot point 1013, where it is gapped, it is a broad bank definitely ditched on the lower slope, now facing south. As it heads up the slope of Rushock Hill the dyke is a considerable bank.
From SO 2900 5900 the dyke heads north-east towards Kennel Wood. On the plateau the dyke is of normal dimensions and character, measuring 13ft on the scarp and 30ft wide overall, with a ditch on the south side. Numerous large boulders are found in the bank. The dyke then suddenly becomes small (1-2ft high) and irregular, and then the dyke becomes clearly defined again with a well-cut ditch, being 26ft wide overall (12ft on the scarp) and the ditch measuring 2ft deep.
