The site sits close to the boundary with the neighbouring townland of Killeen, in ground that is damp enough to make buried features visible from the air, even when centuries of ploughing and grazing have long since erased any trace at the surface.

Cropmarks form when buried walls, ditches, or compacted soils affect how plants grow above them, causing differences in colour, height, or density that become legible only from altitude, and often only in dry conditions when stressed vegetation reveals what lies beneath. The Duntryleague field system was identified precisely this way, on aerial photographs taken on 3 November 1984 for the Bórd Gáis Éireann Curraleigh West-Limerick gas pipeline survey, catalogued as BGE Site 143. Those photographs showed three circular shaped cropmarks alongside linear cropmarks running perpendicular to one another, suggesting a small field system with what may have been enclosures forming part of its layout. A related enclosure recorded separately lies roughly 30 metres to the west. By the time Google Earth imagery was captured in October 2006, two of the circular marks were still discernible alongside the linear features. Later Digital Globe imagery taken between 2011 and 2013, however, showed no surface remains at all, a reminder of how fleeting and conditional this kind of evidence can be.

Visitors to this part of south County Limerick will find nothing to see on the ground today. The site lies in wet pasture and there are no markers, interpretation boards, or formal access points. Its value is archival rather than visual, more useful to someone following the pipeline survey records or the National Monuments Service database than to someone walking the fields. For those interested in how landscapes are read and recorded, the site is a useful illustration of aerial archaeology as a discipline, one that depends on the right season, the right light, and occasionally a gas company's surveying camera rather than any planned investigation.
