Its existence only came to light through aerial photography, which can reveal the subtle geometry of old enclosures, banks, and ditches that are otherwise invisible at ground level, or simply overlooked by earlier surveyors.

The feature measures approximately 16 metres on its northeast to southwest axis and 20 metres on its northwest to southeast axis, making it a modest but reasonably coherent enclosure. It is defined by a scarp, essentially a step or drop in the ground surface, which rises from around half a metre at the northeast to roughly 0.8 metres at the southwest. The southeastern edge has been absorbed into a later field boundary fence, a reminder of how older features tend to be quietly repurposed rather than erased outright. Stones protrude from the scarp at various points, and the interior is anything but flat; hummocks and dips suggest a surface that has been disturbed or built upon at some point, with further stones breaking through the turf, particularly toward the southeast. The most suggestive details lie at the southwestern end, where two parallel narrow trenches, each about 0.9 metres wide and spaced 1.9 metres apart, run the length of the earthwork on a northwest to southeast axis. These may be cultivation features, the kind of shallow ridge-and-furrow traces left by small-scale spade tillage, though the ground conditions made close examination difficult. A heavy growth of hawthorn and brambles had colonised the area, obscuring much of what might otherwise have been easier to read.
