The Limeslade Erratic - the professional analysis

The Limeslade erratic is in no way exceptional. It is simply another giant erratic on the foreshore of southern Britain.

The occurrence of boulders from Pembrokeshire transported by glacier southeastwards across South Wales towards the Severn Estuary has been known for well over a century (reviewed in Scourse, 1997). There is, however, no geochronological or other evidence to support John’s contention that this ice advance occurred during the Anglian glaciation, nor is there any evidence to extrapolate this transport route eastwards from the western Mendips towards Stonehenge

There is no evidence presented by John to shed light on its provenance; rather, the narrative represents a curious journey of local sources to a broad, Wales-wide journey of potential sources of the Stonehenge bluestones, which has no relevance to the identification of the boulder on the foreshore, at Limeslade on Gower, and which logically, on the basis of previously published works, was derived from north Pembrokeshire. This article merely represents a disingenuous cover to justify a rehearsal of the now well-worn and increasingly tedious debate concerning transport of the Stonehenge bluestones.
