There is an ongoing dispute between those who believe that the bluestones at Stonehenge were (a) transported by humans or (b) glacially transported erratics. An igneous boulder found at Stonehenge in 1924 and then lost for over 90 years has been found in Salisbury Museum. Its shape and surface characteristics suggest that it was carried from West Wales by the Irish Sea Ice Stream. The author proposes that most if not all of the 43 bluestone monoliths are glacial erratics.

The radiocarbon dating of Late Iron Age origin and anthropogenic traces such as cut marks on bones of a male elk skeleton found by a local resident in a pit cave prove an archaeological origin. So far known archaeological settlements are several tens of kilometres apart from the finds. The location and the dating are unique in that they are the first evidence of elk hunting during the Late Iron Age in the Bavarian Alps.
