What might look at first like a natural feature is almost certainly anything but. When investigators visited in June 1992, most of the structure was submerged, yet its form suggested deliberate construction, stones piled and arranged rather than deposited by chance. A few trees had taken hold on the exposed portion, giving the spot a quietly incongruous appearance, a miniature wooded outcrop in the shallows.

The site is considered one of six possible crannogs in this part of the lough. A crannog is an artificial or partially artificial island, typically built during the early medieval period as a form of defended settlement, though some examples in Ireland date earlier or later. The Ordnance Survey six-inch map of 1838 records this particular feature as a very small island, measuring around nine metres on its longer axis and six on the shorter, and it reappears on the 1929 revision in much the same form. The consistency across those two surveys, separated by nearly a century, suggests the structure was stable enough above water at those times to be mapped with some confidence. Whether it was ever inhabited, or served some other purpose connected to the lough, remains an open question.
