These monuments typically consist of a horseshoe-shaped or circular mound of fire-cracked stone, built up over centuries of use around a trough that would have been filled with water and heated by dropping in stones from a fire. The mound at Curraleagh was circular, and by the time it was properly noted, it had already been levelled, its internal structure unexamined.

The site appears on both the 1842 and 1937 Ordnance Survey six-inch maps, which at least confirms it was a visible feature of the landscape well into the twentieth century. At some point between those surveys and more recent inspection, the mound was flattened, and the spread of commercial coniferous plantation over the ground has since made any surface examination impractical. Plantation forestry, which became widespread across Irish upland and marginal ground during the twentieth century, has obscured and in some cases damaged many low-lying archaeological features, and Curraleagh is a quiet example of that broader pattern. What the mound concealed beneath the soil, whether a well-preserved trough or burnt spreads indicating repeated use, remains unknown.

The heavy afforestation means there is little to see at ground level, and the site is not accessible in any conventional sense. Its interest lies less in what can be observed and more in what the maps record: a circular mound that existed for long enough to be plotted twice, across nearly a century of surveying, before disappearing under trees and the gradual indifference of changed land use.
