Measuring 1.3 metres in height, roughly 0.75 metres wide and 0.4 metres thick, this prehistoric monument stands oriented along an east-west axis amidst the good pasture land that characterises this part of the river valley. Its modest proportions belie its significance as one of many such ancient markers scattered across the Irish landscape.

Standing stones like this one at Carrick are amongst Ireland's most enigmatic archaeological features, with their original purpose remaining largely mysterious. Erected during the Bronze Age, roughly between 2500 and 500 BCE, these monuments may have served various functions; territorial markers, commemorative stones, or elements in prehistoric astronomical observations. The deliberate east-west alignment of this particular stone suggests it may have held ritual significance, possibly connected to solar observations marking the equinoxes when the sun rises due east and sets due west.

The stone's location in the River Finn flood plain is particularly intriguing, as prehistoric peoples often chose significant landscape features for their monuments. The fertile pastures surrounding the stone would have been equally valuable to ancient farmers as they are today, suggesting continuous human activity in this area for millennia. Recorded in the comprehensive Archaeological Survey of County Donegal compiled in 1983, this standing stone represents just one piece in the complex puzzle of Ireland's prehistoric past, quietly presiding over a landscape that has transformed around it whilst the stone itself remains largely unchanged.
