In this Section photo of Trench 7, Silting Lines are clearly visible in ordinary viewing above 15N. This is likely to be a small and shallow re-cut of the original ditch, the original Cut Line is visible near the right edge of the photo. This Cut Line is seen through the subsoil, from its boundary with the Top Soil to the Trench bottom - here the base of the flint agger. Some Silt Lines can be made out here on the original photo. This ditch may have originally extended to the left of the photo, a weak Cut Line may be visible.
If printed, set margins to 15mm.
