No earthwork breaks the surface, no ditch or bank catches the evening light at a low angle, and no ordnance survey map, historic or modern, has ever shown it. The only record of its existence is a single aerial photograph taken in 1986, in which the outline of an oval shape pressed faintly through a crop, betraying something buried underneath that the ground above has long since swallowed.

The Bruff aerial photographic survey of 1986 captured the enclosure as a cropmark, recorded as survey image Bruff 140 (AP 4/3658). Cropmarks form when buried features, such as the filled-in ditches of ancient enclosures, affect the growth of crops or grass above them, producing variations in colour or height that are invisible from the ground but legible from the air. The enclosure sits roughly 20 metres east of the townland boundary with Gortboy and about 240 metres east of a watercourse. Roughly 125 metres to the south-east lies a ring-barrow, a low circular burial mound of prehistoric origin, recorded separately as LI023-207. The proximity of the two features hints at a landscape that was once considerably more organised than its present agricultural plainness suggests. By the time Digital Globe orthophotos were taken between 2011 and 2013, and again when Google Earth captured the same ground on 28 June 2018, the enclosure had left no discernible trace. The work of compiling and uploading the record was carried out by Alison McQueen and Vera Rahilly.

There is nothing to see at Boherduff in the conventional sense. The field is improved wet pasture, privately held, and the monument itself is entirely subsurface. Its value is archival rather than visual: the 1986 aerial photograph remains the sole evidence of the feature, and anyone interested in it will find more satisfaction in consulting that survey image than in standing at the field boundary. The nearby ring-barrow to the south-east is at least a physical presence in the landscape and may offer the more grounded impression of what this corner of Limerick once contained.
