This standing stone at Magherashanvally is notably absent from the first edition of the Ordnance Survey 6-inch map, suggesting it may have been overlooked by early surveyors or perhaps considered too unremarkable to warrant inclusion. The boggy terrain surrounding the stone likely made access difficult for Victorian cartographers, contributing to its omission from historical records.

The stone’s location in wetland is fairly typical for such monuments across Ireland; many prehistoric peoples deliberately chose liminal spaces between dry land and water for their ritual sites. These marshy areas were often considered sacred boundaries between the earthly and spiritual worlds. The waterlogged conditions that may have deterred mapmakers have ironically helped preserve the monument, as boggy ground tends to discourage agricultural development and casual interference.

This particular standing stone was properly documented during the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983. Their systematic fieldwork brought attention to numerous overlooked monuments throughout the county, cataloguing sites from the Mesolithic period through to the 17th century. The survey has since become an invaluable resource for understanding Donegal’s archaeological landscape, with entries regularly revised and updated as new information comes to light.
