VII.—The Scottish Kames and their Evidence on the Glaciation of Scotland

Published online by Cambridge University Press:  06 July 2012

Extract

The word “kame” is regarded by one usage as the Scottish equivalent of the Irish term “esker”; according to another usage, the terms are not synonymous, for an esker is regarded as the British representative of the Swedish “osar” and as a ridge of sand and gravel deposited along the course of a river within a glacier, while a kame is a ridge of similar materials deposited outside the glacier along its edge. The Polmont kame, as seen from the railway, strikingly resembles the Swedish osar; but it and those at Carstairs, the best known of Scottish kames, proved, on examination, not to have the cross-banding characteristic of osar, and to be marginal deposits. The typical Irish eskers are also marginal deposits (Gregory, “The Irish Eskers,” Phil. Trans., A, 210, pp. 115–51) and of the same origin as the Polmont and Carstairs kames. A few small Irish eskers have the structure of osar, while many are the remnants of denuded sheets of sand and gravel. I therefore suggested that the term esker, being Irish in origin, should be applied generally, as it is in Ireland, to hills of glacial sand and gravel.

page 421 note * I was surprised to find at Gleneagles a patch of sand with marine shell fragments at the height of a little above 500 ft. This had been dropped during the construction of the bunkers; as that level is critical in regard to the height of the sea in late glacial times in eastern Scotland, I inquired as to the source of the sand. Mr D. Matheson kindly had the sand traced, and informs me that it was brought from the Fifeshire coast.

page 425 note * Since this paper was read a Geol. Surv. Memoir has been issued, Sheet 103, Golspie, which briefly describes this kame, and adopts for it (p. 121) an explanation, according to which it would be an ispatinow, as defined on p. 395.
