The pairing is not accidental. The standing stone is oriented southwest to northeast, and viewed from the northwest the two stones read as a single composition against the open sky, which may well have been the point.

The standing stone is a sandstone conglomerate, a rock type formed from compressed gravel and pebbles, rising between 1.45 and 1.8 metres depending on which end you measure, widest at the base and tapering sharply toward the top. It sits roughly 0.4 metres from the edge of a gravel quarry, which makes its continued survival something of an accident of recent history. The boulder beside it is a glacial erratic, meaning it was carried to this spot not by human hands but by ice-age glaciation and left behind when the ice retreated. At 2.8 metres long and 1.8 metres both wide and tall, it is one of the largest on the ridge. Several other erratics are scattered across the area, but this one, also a sandstone conglomerate, clearly influenced the placement of the standing stone. The monument was listed in the Record of Monuments and Places in 1996 as a megalithic structure, a broad category that covers prehistoric stone monuments of various kinds, though nothing more precise about its date or purpose is recorded.
