These features, known as fulachtaí fia, are among the most common prehistoric monuments in Ireland, yet they remain genuinely poorly understood. The name, loosely translated as "cooking place of the deer," refers to a type of site found typically beside a stream or boggy hollow: a trough, often timber-lined, that would have been filled with water and brought to the boil by dropping in stones heated in a nearby fire. Once the stones cracked and became useless, they were discarded into the characteristic horseshoe-shaped mound that survives today. Whether these sites were used primarily for cooking meat, processing hides, brewing, or bathing is a question archaeologists continue to debate.

Fulachtaí fia are dated broadly to the Bronze Age, roughly 2000 to 500 BC, though some examples fall earlier or later. They cluster in low-lying, waterlogged ground, which is partly why so many survive; the same wet conditions that made the locations practical for ancient use also helped preserve the mounds beneath peat. Mayo, with its bogland landscape, contains numerous examples, and Carrowkeel is one of several townlands across Ireland that carries the name, derived from the Irish An Cheathrú Chaol, meaning "the narrow quarter." Beyond the monument's classification and location, the specific details of this particular site, its dimensions, condition, and precise setting, are not currently in the public record.
