Area of looser fill caused by plough scar. This deposit should be considered part of the plough zone. It was excavated separately because when the area below the plough zone was cleaned, there was a hard straight edge here with loose deposit abutting bricky material. The loose deposit was assigned A-012 and removed to investigate if it was abutting a wall, but the straight edge turned out to be a plough scar and A-012 was just a small area of plough zone deposit
