You are quite right that the ground between the present shore and the foot of the bank is indeed raised beach, as can be seen even better along the road at Carnain, and was created as the land rose. However, I wasn't referring to that but to the steep bank and the extensive ground behind it which is certainly not raised beach though, as I said, often wrongly called that. If you walk up up the lane which cuts through it to the old quarry where Calum dumps various old vehicles, etc., you can see that the quarry has been dug into a mass of sand and irregular stones typical of what flows out from under a glacier. There are none of the smooth round pebbles which form a beach. <br />So, we have a raised beach backed by glacial outwash with its seaward face cutaway by the sea. Agreed?<br />As all my friends will say, I hate to be pedantic (!), but the present shore is to the south of the road and the raised beach and bank are to the north, as the road runs pretty much east-west!<br />MalcolmAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8339296866231719936.post-20536289246931020792011-02-14T15:14:45.860+00:002011-02-14T15:14:45.860+00:00Rather than sea level falling, the land rose.

Subsequent to the sea level rise at the end of the ice age, the land rose, through isostacy, and the raised beach on which the road runs, was revealed.<br /><br />So on the east side of the road we have a beach, and on the west side of the road we have a raised beach. <br /><br />I therefore will continue to refer to this as a raised beach. <br /><br />Iain M CampbellAnonymousnoreply@blogger.com
