Yet the standing stone at Aughacasla tends to pass without much notice, partly because it sits in a landscape that seems almost too ordinary for prehistoric monument-making: level ground, open sky, the bay nearby. Its irregular shape narrows as it climbs, and its long axis runs roughly east-southeast to west-northwest, an orientation that may have had calendrical or ceremonial meaning to whoever raised it, though no written record survives to say so.

What gives the stone an additional layer of interest is evidence of deliberate arrangement at its base. A survey note from 1947 recorded that the ground immediately around it had once been paved and ringed by a kerb of smaller stones set on their ends, sometimes called foot stones. This kind of kerbed setting around a standing stone suggests the site functioned as more than a simple marker; it implies a maintained, possibly sacred space. The stone itself measures just over a metre across at the base and just over half a metre in depth, tapering towards the top. The archaeological survey of the Dingle Peninsula, published by J. Cuppage in 1986 as part of the Corca Dhuibhne survey, catalogued it and recorded what remained of these features at that time.
