No earthwork, no stonework, no visible surface trace of any kind. What is recorded here is a midden, one of several such features noted in the area, and its entire existence as a recognised site rests on a single line in a nineteenth-century publication.

A midden is, in essence, a rubbish heap, typically composed of discarded shells, bones, and other organic domestic waste deposited over time by people living or working nearby. They are among the more quietly informative types of archaeological site, because the accumulated debris of meals and daily life can reveal a great deal about diet, season of occupation, and the way communities interacted with a coastal environment. The Ballyvodock example was among several described as "heaps of shells" by a writer named Atkinson in 1874. That brief notice is the main thing keeping this location on the archaeological map. Whether the shells are still present below ground, disturbed, or entirely gone is not recorded.
