Very spotty spotted dolerite

 

 

This is the memorial stone to WR Evans, located at Glynsaethmaen, on the south side of the main Preseli ridge.  It has been bashed about and sand blasted, so we can't say anything about its shape,  except that it has been used as a gatepost before being donated for use as a memorial stone.  Note the weathering patina on the lower part of the front.  This may have formed over recent decades, assisted by the presence of a rusty broken gate hanging bolt......... 

The stone is VERY spotty -- and it is most likely to have come from Carn Meini -- this tor was used in historic time as a nice source for gateposts.

 

Thanks to Hugh Thomas for the pic of a broken metal pin or chisel in a crack up on Carn Meini.  Rock -- spotted dolerite.   Presumably a trace of an attempt by a local farmer to extract a nice handy gatepost, back in the day..........
