Whilst nothing remains visible today, this prehistoric monument left enough of an impression to be recorded on historical Ordnance Survey maps; marked as 'Standing Stone' on the second edition 6-inch map and later noted as 'Gallan (site of)' on the third edition. The Irish term 'gallan' refers to a pillar stone, typically one that was erected during the Bronze Age as a territorial marker, burial monument, or for ceremonial purposes.

The site sits on what archaeologists describe as good quality land, suggesting this location was deliberately chosen by its ancient builders. Standing stones like this one were often placed in prominent positions within the landscape, serving as waymarkers or focal points for prehistoric communities. The fact that it warranted inclusion on multiple editions of the OS maps indicates it was likely a substantial monument that remained standing well into the modern period before its eventual disappearance.

Today, visitors to Whinny Hill will find no trace of this ancient marker, yet its documented existence adds another layer to Donegal's rich archaeological tapestry. The stone's disappearance, whilst unfortunate, is not uncommon; many such monuments across Ireland have been lost to agricultural improvements, stone robbing for building materials, or simply toppled and buried over time. Its memory persists through the careful work of surveyors and archaeologists who documented these sites before they vanished completely from the Irish countryside.
