The mound has been levelled entirely, leaving behind what archaeologists call a spread of burnt material, the characteristic debris of a fulacht fia.

A fulacht fia is a type of Bronze Age cooking or processing site found in considerable numbers across Ireland, particularly in low-lying, often waterlogged ground. The typical arrangement involved a trough dug into the earth, filled with water, and heated by dropping fire-heated stones into it. Those stones, once cracked and spent, were tossed aside, gradually building up into a horseshoe-shaped mound. Over centuries, these mounds accumulated layers of shattered, heat-reddened stone and charcoal-dark soil. Thousands survive across the Irish landscape in various states of preservation. The example at Tullig More represents one of the more reduced survivals, its mound gone, its presence now registered mainly through the burnt stone scatter that such sites leave behind when disturbed or eroded. Whether through agricultural activity or gradual attrition, the raised element that would once have marked this spot has been lost to the surrounding land.
