The photograph, part of the Cambridge University Collection of Aerial Photography, revealed a pattern of long boundaries dividing an undulating eastward-sloping field into four irregular strips of varying width. On the ground, nothing of those boundaries remains visible today.

What makes the site quietly puzzling is its absence from the cartographic record. The Ordnance Survey mapped Ireland at six-inch scale in the early 1840s, and again around 1904, and neither edition shows any trace of these field divisions. That double absence suggests the boundaries had already fallen out of use, and possibly out of recognisable shape, before Victorian cartographers arrived with their instruments. The working assumption is that the field system pre-dates 1840 and may be connected to the historic settlement of Ballynaclogh itself, though no firmer date has been established. Since 1969, housing has spread northward along the road, and a small cul-de-sac has been built into the southern end of the site, further erasing whatever traces the aerial photograph once captured from above.
