Notable gaps in the known distribution include south-eastern, south-western, and north-western England. The overall distribution of cursus extends into Wales and Scotland. The majority of recorded cursus lie on the flat well-drained gravel terraces of major river valleys, but this may again be a product of aerial photography being the main source of new discoveries. Examples are known on the chalk downlands of Dorset and Wiltshire, and there are several examples in northern England, as for example around Rudston on the Yorkshire Wolds. Larger cursus tend to cut across the natural grain of the countryside, whereas shorter cursus are often set out on a single gently sloping block of land. Cursus set on higher ground tend to run along the spring-line, while those on lower ground frequently lie at right-angles to a river or stream. Some cursus run between two rivers, and at Stanwell, Surrey, the cursus appears to cross two rivers. Little regional variation in type can be detected at present, although there is a tendency for the square-ended cursus of type B to cluster in central England and East Anglia. One Scottish variation in cursus form already noted is the use of closely-set pits rather than ditches to define the perimeter.
