The mound measures roughly 16 metres east to west and 7 metres north to south, its southern edge cut away by a drain and a field fence. A further dump of burnt material sits against that same fence about 12 metres to the east, suggesting the original deposit was disturbed at some point, probably during agricultural work.

This is a fulacht fia, a type of prehistoric cooking site found in enormous numbers across Ireland, typically dating to the Bronze Age. The basic principle involved heating stones in a fire, dropping them into a water-filled trough to bring it to the boil, and using that hot water to cook meat. Over repeated use, the stones would shatter from thermal stress, and the discarded fragments accumulated into the horseshoe-shaped or oval mounds that survive in the landscape today. What makes the Propoge example particularly interesting is that it does not sit in isolation. It belongs to a cluster of three such monuments in the immediate area, the other two recorded nearby, which hints at sustained activity in this part of north Cork over a considerable period, or perhaps seasonal returns to a favoured location close to a reliable water source.
