The enclosure at Garrane has been levelled, leaving no surface trace whatsoever, and a visitor standing in the pasture beside the conifer plantation would have no reason to suspect that anything of significance ever occupied this particular patch of ground.

What makes its absence worth noting is the paper trail it left behind. The Ordnance Survey's six-inch map of 1842 recorded it clearly, using hachuring, the system of short lines surveyors used to indicate raised earthworks, to mark a roughly circular enclosure approximately eighteen metres in diameter. By the time the same landscape was mapped again in 1903 and once more in 1937, the feature had softened in form, appearing as an oval raised area measuring around eighteen by fifteen metres. Enclosures of this type, often referred to as ringforts, were among the most common settlement forms in early medieval Ireland, typically consisting of a circular bank and ditch enclosing a domestic area. That the 1842 surveyors felt it worth recording suggests it still had some presence on the ground at that point. Sometime between the mid-nineteenth century and today, it was levelled entirely, most likely through agricultural improvement.

The cartographic sequence, three separate map editions each capturing a slightly different version of the same disappearing feature, offers a quietly useful illustration of how the archaeological record erodes. The site itself is gone, but the maps preserve its outline like a fading impression.
