It's absurd to call Carn Ingli a volcano. The only justification of this description is that it looks a bit like one, but its shape is entirely an artifact of recent glacial action. The hill exists because of the presence of a number of hard tilted intrusive sills. There are no extrusive rocks in the neighbourhood, nor is there a 'plug' formation. The volcano that gave rise to the Carn Ingli sills was somewhere out in the Irish Sea. So references to a 'volcanic profile' and a 'time of last eruption' are incorrect. . . .LinguisticDemographer 10:40, 15 May 2007 (UTC)
