These monuments typically consist of a horseshoe-shaped mound of fire-cracked stones beside a trough, where water was heated by dropping in stones from a fire. What made the Meenahony example worth recording was its clear relationship to a nearby spring, the kind of reliable water source these sites almost always required.

When P. J. Hartnett noted the site in 1939, it measured eighteen by thirty feet and opened to the north, directly towards the spring well. That orientation was almost certainly deliberate, allowing easy access to the water that made the whole cooking or heating process possible. The mound has since been levelled, leaving nothing visible above ground. Hartnett's brief description, recorded in 1939 and published in the Archaeological Inventory of County Cork, is now the main surviving account of what was once a tangible feature in this corner of the county.
