The buried remains of a Neolithic long barrow, situated 465m north-west of Dexthorpe (in Langton by Spilsby parish). The barrow is located on a south facing slope, overlooking a tributary of the River Lymn, and below the source of the Skendleby Beck. Although the monument cannot be seen on the ground, it is clearly visible as cropmarks on aerial photographs, in the form of an elongated oval enclosure defined by an infilled and buried ditch measuring about 75m long by 25m, and orientated east-south-east by west-north-west. The ditch circuit is thought to be unbroken by a causeway, suggesting that the remains represent a type of Lincolnshire Wolds long barrow which in this case did not culminate in the construction of a mound. For the full description and the legal address of this scheduled monument please refer to the appropriate entry in the National Heritage List for England. {1}{2}{3}{4} This long barrow lies roughly 90m above sea level, on an upper, north facing slope at the head of the valley. It is aligned north-north-west by south-south-east, with the long axis traversing the contours. It takes the form of an elongated elliptical chalk mark, bounded by the dark line of the surrounding ditch, and measures roughly 72m by 20m. No apparent gaps can be seen in the encircling ditch. The Spellow Hills long barrow lies on the opposite side of the valley, 450m to the north. Lines of levelled ridge and furrow cultivation appear to extend across the field. {5}{6} More recent analysis of the aerial photographic evidence saw the barrow as a faint chalky soilmark, aligned on a north-west to south-east axis. It measured c.68m in length and was 15.5m wide at the southern end, tapering to 12m across at the narrower northern end. There was the suggestion of some spread earthwork remains for the southern half of the barrow, as noted on a digital elevation model of the site. {7}
