 Location Grinton, Harkerside Moor. High Harker Hill, Long Scar and Grove Beck
 Civil Parish Grinton
 Brit. National Grid SE 028 975
 Altitude 415m
 Geology The Main Limestone. Long Scar appears to be a fault scar with overturned vertical limestone strata visible in scree below the cliff. (Inf. John Russell).
 Record Name The GrintonFremington Linear Dike System, Part One: Linear earthwork at High Harker Hill centred on Long Scar and Grove Beck Head.
 Record Description This record is a photographic description of the linear earthwork which has been the subject of recent excavation by SWAAG under supervision from ASDU at a storm washout section SE of Grove Beck. See excavation images.

This linear earthwork incorporates the limestone cliff of Long Scar to extend for a total distance of 750m NE from Grove Beck. Immediately north east of Grove Beck, as far as Long Scar, the earthwork comprises an infilled main ditch which may have been quarried into the limestone rock, berm and only slight traces of a stone bank. The earthwork continues from the NE end of Long Scar and here the earthwork is topped by a very substantial limestone bank with visible facing stone, see photo, which may indicate the presence of a faced rampart wall here. As with the excavated washout section this upper banks was formed from material excavated from a rear ditch. This upper bank/rampart which was carried round the end of the ditch terminus at SE028975 some 750m NE of Grove Beck, see photos, signifying that the earthwork was indeed completed and not left incomplete as may be otherwise considered.

South east of Grove Beck, the earthwork extends only for a distance of 200m to the unnamed sike at SE . Here the Dike, as excavated, consists of a shallow round bottomed ditch,remains of a counterscarp bank , berm and an upper bank formed from material excavated from an upper ditch which has a very similar round based profile and similar fill to the main ditch. SE of Grove Beck the Dike has been cut through by a very active storm water washout (the excavation site) and by several old inactive washouts.
 Dimensions Total length of this Dike, including Long Scar, is 950m
 Additional Notes It is intended to provide a similar record of each of the remaining Dike Sections which together form the Grinton-Fremington Dike System.
