Carn Goedog

This isolated humpbacked outcrop is 1.65 km WNW of the main Carn Menyn outcrops at SN128.332. It is composed of dolerite rocks and is located at the foot of a deep slope immediately to its east, which is effectively the terminus of the Carn Menyn ridge. Investigator Wozencroft went down to the outcrop while Devereux initially stayed near the top of the eastern slope. It was found that Goedog had many lithophones, and that they could be clearly heard by Devereux fully 300 m away (and could doubtless be heard much further away than that). The first picture here shows Goedog from Devereux’s position, and the sound clip is the recording of a lithophone being struck at Goedog at that distance.


The most recent petrographic and lithogeochemical analyses of samples of bluestones at Stonehenge indicate that their sources are either the specific Carn Menyn outcrops or Carn Goedog. The actual Stonehenge bluestones implicated are those numbered 33, 37, 43, 49, 65, 67, and 61 on the monument’s site plan. We found that Goedog was comprised of many lithophones, though a detailed assessment of numbers was not made. Our general guesstimate was that about 10 percent of the rocks were lithophonic, though there may be higher concentrations in localised areas.

The remaining 8 pictures on this webpage show various views of and from Carn Geodog, along with a small selection of lithophone sounds from the outcrop.

General view of Carn Goedog from the east, and from the location where this (unenhanced) sound clip was recorded. (Because the recorder was exposed high up on the slope, wind noise is a factor on the recording—as it was actually at the location, of course. Yet the lithophone sounds are clearly audible.) It is evident that lithophonic sound can carry considerable distances, and so one function of lithophones, ringing rocks, may have been for signalling purposes, or calling the faithful to whatever form of Stone Age worship or ceremony, much like church bells in a Christian context
