Measuring roughly fifteen metres along its northeast-to-southwest axis and eight metres across, it is the kind of feature that could pass for a patch of disturbed earth to most walkers. It is, in fact, a fulacht fia, a type of prehistoric cooking site found in considerable numbers across Ireland, typically dating to the Bronze Age. The usual interpretation is that stones were heated in a fire and then dropped into a water-filled trough to bring it to boiling point, a process that gradually produced the mound of cracked, fire-reddened stone and darkened soil that survives today.

The site was first recorded in 2000, and what makes it slightly more interesting than a single such feature might suggest is that a second possible fulacht fia lies approximately ten metres to the north. The clustering of two such sites so close together is not unheard of across Ireland, but it does invite questions about how intensively this particular slope was used and over what period. The Little Sugar Loaf, the smaller of the two Sugar Loaf hills in Wicklow, provides a sheltered, south-east-oriented gradient, which may have made the area attractive for repeated activity. Whether the two sites represent broadly contemporary use or separate episodes of occupation at different points in prehistory is not something the surface evidence can settle.
