They form no coherent pattern, follow no obvious logic, and leave no dramatic impression on the landscape. They are, in almost every measurable sense, unremarkable to the naked eye.

What revealed them was not an excavation or a chance discovery, but a flight. In July 1967, aerial reconnaissance using a Cambridge University Collection of Aerial Photography sortie, recorded as CUCAP ATF 53, picked out a series of very low earthen banks spread across a roughly rectangular area of about 450 metres northeast to southwest and 250 metres northwest to southeast. Aerial photography has long been one of archaeology's more quietly revelatory tools: crop marks, soil discolouration, and the way low sunlight catches slight changes in ground level can expose features entirely invisible at surface level. At Liskeevy, what the camera recorded was the ghost of a field system, boundaries that once divided and organised this patch of ground for purposes and by people now unknown. The earthworks are described as very poorly preserved, which places them at the more elusive end of the archaeological spectrum, where interpretation remains cautious and open-ended.
