6 metres north to south, 2.3 metres east to west, and standing 0.75 metres high. What makes this particular cairn noteworthy is the flat slab positioned upright on its summit; a stone measuring 0.88 by 0.43 metres and just 10 centimetres thick. This serves as the ninth station of St. Columbkille's turas, a traditional pilgrimage route, though the exact age of these features remains uncertain. The 6-inch Ordnance Survey sheet identifies it as a 'Penitential Station', hinting at its religious significance in local tradition.

Archaeological testing in February 2006 revealed little about the cairn's origins but provided insights into the surrounding landscape. When developer Richard Crumlish conducted pre-development testing for a housing project near the site, five machine-excavated trenches exposed layers of blue-grey sandy clay beneath the topsoil, followed by peat deposits up to 1.3 metres thick, with more sandy clay and bedrock below. The only find was a modern glass bottle in the topsoil, and apart from some fill dumped by developers in 2005, the stratigraphy appeared entirely natural and undisturbed.

The cairn's connection to St. Columbkille's turas places it within a living tradition of pilgrimage that continues in Glencolumbkille, where devotees still follow ancient paths marked by stone stations. While its antiquity cannot be definitively established, its inclusion in the Archaeological Survey of County Donegal ensures its recognition as part of the county's rich tapestry of field monuments, spanning from the Mesolithic period to the 17th century.
