Field systems of this kind are among the quieter presences in the Irish landscape: banks, ditches, or stone walls arranged in patterns that predate modern agricultural divisions, occasionally prehistoric, occasionally medieval, and often stubbornly resistant to precise dating without excavation.

The site was noted by Judith Cuppage in her 1986 survey of the Dingle Peninsula, catalogued simply as an "old field system" with no further elaboration. That brevity is itself telling. The Dingle Survey was a thorough undertaking, and when even a careful surveyor leaves a site at two words and a catalogue number, it usually means the physical remains were either too degraded, too ambiguous, or too overgrown to describe with confidence at the time of recording. Na Gleannta Thuaidh sits in a part of Kerry where the land has been worked and reworked across many centuries, and where the archaeology tends to accumulate in layers that resist easy interpretation from the surface alone.
