It appears on the 1837 Ordnance Survey six-inch map as a neat oblong, roughly 16 metres north to south and 11 metres east to west, already clipped at its southern edge by a trackway. By the revised 1913 twenty-five-inch survey it had grown, or at least spread in the cartographers' estimation, to an oval of approximately 38 metres by 21 metres, with curiously straightened sides. By 1983, a survey found no surface remains at all, just a modern plantation occupying the space. What it actually was remains an open question.

The best working theory places this feature within the broader project of landscaping the demesne lands of Mount Dalton House, now known as Loughazon Hall, which sits about 340 metres to the east. Designed landscapes of the post-1700 period in Ireland frequently incorporated decorative plantings, ornamental ponds, and tree-rings, the last being circular or oval arrangements of trees intended to punctuate a view or anchor a focal point within a managed estate. The lough visible to the south would have made this hillside slope a natural candidate for some kind of considered intervention. Whether the feature began as a pond, a planted ring, or some combination is unclear, but it was never recorded as an antiquity on any edition of the Ordnance Survey six-inch maps, which suggests it was always understood, when it was understood at all, as a relatively modern estate embellishment rather than something older.

The site is now obscured beneath tree cover, and nothing is visible at ground level. What survives is the outline, preserved only in successive maps that tracked something shrinking and shifting across the decades, and the slight puzzle of why it changed shape so dramatically between one survey and the next.
