The site, also known as the burial ground at Doire Leathan, is surrounded by a stone wall with a single entrance gap facing east-northeast. Though the flat interior shows signs of agricultural disturbance from ploughing over the years, it retains its character as an ancient place of rest.

Local memory preserves an intriguing detail about this graveyard; a cross-inscribed stone once stood in the north-northwest section, though it has since vanished from the site. What remains in its place is a natural erratic boulder, a glacial remnant that now serves as the only stone marker in that portion of the grounds. Whether the inscribed stone was removed, destroyed, or simply lost to time remains unknown.

The site was documented as part of the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983. This ambitious project catalogued field antiquities spanning from the Mesolithic period through to the 17th century, preserving knowledge of places like Garrynakilla that might otherwise fade from collective memory. The burial ground stands as a quiet testament to the generations who once lived, died, and mourned in this corner of rural Ireland.
