There is nothing to see from the surface, no mound, no earthwork, no obvious trace. The only evidence for their existence comes from the air, specifically from a set of aerial photographs taken in 1966, which captured circular cropmarks spread across the landscape in a roughly linear arrangement. Cropmarks of this kind form when buried features, such as filled-in ditches, affect the growth of crops or grass above them, producing rings or lines that become visible from altitude even when the ground itself appears featureless.

The circular marks at Lisduff most likely represent a barrow group, a cluster of prehistoric funerary monuments that would originally have served as burial sites. A barrow, in its most familiar form, is a mounded earthwork raised over a grave or series of graves, often surrounded by a circular ditch. Here, however, the mounds appear to have been levelled entirely, leaving only the ditches as subsurface traces. Because no outer enclosing bank can be identified from the photographs, the monuments have been classified as ditch-barrows rather than ring-barrows, a distinction that turns on the absence of that outer earthen rim. The group stretches in a loose line across land that was originally marshy, close to the Munster river to the south-east, and which has since been drained and brought into agricultural use. One monument at the north-east end of the alignment is noticeably larger than the rest. Alongside the barrow group, the 1966 photographs also reveal traces of an ancient field system to the west, consisting of two parallel linear ditches, with further single ditches to the south and east, suggesting that this was once an organised and inhabited landscape well beyond the burial sites alone.
