These monuments typically consist of a horseshoe-shaped mound of fire-cracked stone and charcoal-dark soil, accumulated over years of boiling water by heating stones in a fire and dropping them into a trough. They are among the most common archaeological features in the Irish landscape, yet most people have never heard of them, and a great many have been quietly destroyed by centuries of farming and drainage work.

At Churchpark, the evidence is fragmentary and uncertain. In the western terminal of a field bank running along the southern side of a stream gully, a layer of angular stone fragments embedded in black soil has been exposed. On the opposite bank, a thin lens of dark soil is visible in section just beneath the sod. Whether these are the original deposits in their undisturbed position, or material that was simply scooped up and incorporated into the field bank at some point, could not be determined. The stream itself, which flows to the south-east through damp, boggy ground, has been subject to dredging, and heaps of upcast material now line the northern bank. That intervention may have disturbed or dispersed whatever survived here. The site sits in pasture, and the combination of agricultural drainage work and the reuse of old material in field boundaries has left the archaeology in an ambiguous state, present enough to notice but damaged enough to resist easy interpretation.
