This surface soil and regolith layer is in places up to a metre thick. The pits are up to 50 cm deep, and they have survived quite happily since the Bronze Age -- believe me!! They are not sockets like the pits at Stonehenge, but they are pits nonetheless.BRIAN JOHNhttps://www.blogger.com/profile/00413447032454568083noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-7609966173475431312011-09-12T17:45:39.898+01:002011-09-12T17:45:39.898+01:00Brian you write,

And I further assume that these “stone pits” had to be in the underlying bedrock and not in the top soil. Otherwise, how could these pits have survived? <br /><br />So my questions:<br /><br />1) When glaciers deposit erratics on the surface of a landscape, do these erratics form pits in the bedrock?<br />2) What makes up the bedrock where Carn Briw is located? I assume it is not chalk? <br />3) How deep are these pits, and what similar features these have with the “empty pits” under the Stonehenge Layer?<br />4) Are there similar “empty pits” found around every mound where stones where collected?<br /><br />KostasConstantinos Ragazashttp://knol.google.com/k/constantinos-ragazas/the-un-henging-of-stonehenge/ql47o1qdr604/16#noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-71618635287195085042011-09-11T19:48:12.096+01:002011-09-11T19:48:12.096+01:00Thanks!

Sometimes there is a hummocky surface expression, as around the Pomt Ceunant moraine I described some time ago. On some of the steeper slopes there are screes -- made of nothing bit angular stones of all shapes and sizes. The burial mounds are usually pretty distinctive -- made of whatever local stones were lying around, and piled high into mounds. They occur mostly on summits and ridges -- but that may be because the lowland ones have been destroyed?BRIAN JOHNhttps://www.blogger.com/profile/00413447032454568083noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-23803720351867781362011-09-11T17:45:26.587+01:002011-09-11T17:45:26.587+01:00So Brian, are these fields of stones scattered abo...So Brian, are these fields of stones scattered about sparsely and not in concentrated piles as with burial mounts?

In some places (as at Carn Briw) you can actually see the pits all around the mound, from which the stones were collected. Nice and simple -- and eminently sensible.BRIAN JOHNhttps://www.blogger.com/profile/00413447032454568083noreply@blogger.comtag:blogger.com,1999:blog-1228690739485734684.post-70309323582578809022011-09-11T15:20:01.455+01:002011-09-11T15:20:01.455+01:00Brian,
What I find rather interesting about this ...Brian,<br /><br />What I find rather interesting about this Carn Meini tomb is the large concentration of stones in a small area on what looks like the side of a hill. Is similar concentration of stones common in the landscape of Wales and southern UK? Are there, instead, fields with many stones scattered about sparsely over a large flat area? <br /><br />Another instance of mounts of stones I clearly remember are the vaulted chamber tombs photos you posted awhile back of some small island off Brittany when you last visited there. That left an impression with me. But those stones were smaller and more 'tile-like'. But such a massive mount of them! More than would be structurally needed to built a burial vaulted chamber.<br /><br />The shape of these stones at the Carn Meini tomb do not look to me like the kind you could even built a wall, let alone a vaulted chamber.<br /><br />Also, looking at the photo of the Carn Meini tomb you posted, there seem to be some white spots on many of these stones. Are all of these the same as the bluestones at Stonehenge? <br /><br />KostasConstantinos Ragazashttp://knol.google.com/k/constantinos-ragazas/the-un-henging-of-stonehenge/ql47o1qdr604/16#noreply@blogger.com
