Two trial trenches were positioned to investigate several linear cropmarks, including part of a rectangular enclosure. Whilst visible as cropmarks, these features were not identified during the geophysical survey.

Three ditches were encountered in the first trial trench, the earliest of which had a slight curving E-W alignment and a suggested entrance point. It was truncated at its eastern end by two parallel N-S ditches, which appeared to correlate with the cropmark enclosure. Four sections were excavated through showing it to have a V-shaped profile, just 0.15m deep. No finds were recovered from its silty sand fills. Sections through the two N-S ditches also failed to recover and finds, but showed these (enclosure) ditches to be slightly more substantial.

Five parallel E-W ditches were identified in the second trial trench, of which three were investigated. The southern-most ditch appeared to correspond with the enclosure identified in the first trial trench. It had a V-shaped profile, filled with two deposits of silt sand. To its north was another ditch, which had a shallow U-shaped profile, also filled with two deposits of silt sand; the latter of which contained a fragment of a medium-sized mammal bone. A shallow ditch investigated in the central part of the trench appeared to be the remnants of a post-Medieval plough furrow.

The earliest ditch identified in the first trial trench was not visible on the cropmark plot or the geophysical survey. It appears to be part of a slight enclosure of unknown date, which had a narrow entrance on its southern side.

Two of the later, N-S ditches (identified in both trenches) correspond with the cropmark of an enclosure. The date of the features remains unknown, with the only finds being a single animal bone. It is likely, however, that the features are part of the Iron Age agricultural landscape identified elsewhere on the Site.
