At the eastern end of a long ridge, an isolated rock bears two weathered cup marks on its upper surface, though time and vegetation have partially obscured these ancient carvings. These simple circular depressions, known as cupmarks, were pecked into the stone thousands of years ago, possibly serving ritual or territorial purposes that remain mysterious to modern observers.

Just north of this marked stone lies a large block that carries its own story, albeit a more recent one. According to the local landowner, this substantial stone once stood upright as part of the prehistoric landscape until it was toppled in 1984. While its original purpose and exact age couldn't be definitively established during Van Hoek's 1987 survey, its proximity to the cup marked stone suggests it may have been part of a broader ritual complex that once dominated this ridge.

These modest archaeological features, catalogued as part of Donegal's extensive prehistoric heritage, represent the kind of understated ancient sites that dot the Irish landscape. Unlike grand passage tombs or elaborate stone circles, these simple marked stones and fallen monuments speak to a more widespread tradition of marking the landscape that stretched across prehistoric Ireland, leaving subtle traces that require a keen eye and local knowledge to fully appreciate.
