Soilmarks of a ditched, elongated oval mound with convex ends, slightly concave sides and traces of internal features. Identified on aerial photographs examined as part of the National Mapping Programme. {1}{2}{3} The monument includes the buried remains of a Neolithic long barrow located on the eastern valley slope of a tributary of the River Bain. It is situated in an area of arable land known as Heath Road Field, about 575m south-west of Warren Manor Farm, Welton le Wold. Although the monument cannot be seen on the ground, its uninterrupted ditch is clearly visible from the air as a cropmark on aerial photographs. The monument is aligned east-west and measures approximately 55m long by 30m wide. The ditch has slightly convex sides and rounded ends and its form is thought to represent a simpler type of this class of monument in which the ditched enclosure set aside for mortuary activities would not have been elaborated by the construction of a large earthen mound. The remains of structures associated with these activities will survive as buried features. The monument is one of a number of Neolithic and Bronze Age barrows associated with the Bluestone Heath Road which is thought to have originated as a prehistoric trackway. Although the barrow has been degraded by ploughing, it will retain valuable archaeological and environmental evidence in and on the buried ground surface and within the fills of the encircling ditch. These deposits will provide rare information concerning the barrow's dating and construction and the sequence of mortuary ritual at the site, and will illustrate the nature of the landscape in which the monument was set. For more detail see scheduling document 27892. {4} The long barrow is situated at the head of a dry valley, on the tip of a low spur where the valley forks, and is 200m east of the Bluestone Heath ridgeway. It is aligned east to west, and the long axis runs parallel with the contours. It is a trapeziform enclosure with a convex west end, the east end is more straight. A probable causeway shows in the ditch circuit at the east end. The west half of the enclosure appears to have a large ring ditch superimposed upon it, the east arc of which is most clearly defined as cropmarks. {5}{6} The barrow appears on more recent aerial photogrpahy as cropmarks and soilamrks, and as a shallow earthwork. It is defined by an oval ditched enclosure, orientated west to east with dimensions measuring 35.5m by 22.5m. What had been interpreted above as a superimposed round barrow now appears much more likely to be an extension of the long barrow to the east, adding a further 12m to the length. {7}
