Indications of the Ice-age in Shetland

Abstract

SHETLAND will now be narrowly searched for proofs of glacial action by every tourist who takes an interest in such vestiges of a bygone era. Smoothed surfaces, striæ, and grooves are so abundant and distinct on Mr. Peach's ground—the sandstones on the shores of the Loch of Clickhemin, and of the immediately adjoining bay—as to have long ago suggested the innocent or waggish notion that the last were scratches made by the prows of the Norsemen ! Still on the mainland, but some forty miles distant, on the shores of the magnificent bay of St. Magnus, striæ are to be seen on the sandstones of the baaf-fishing station at Stennis, and till, or boulder-clay, lies in patches on the Tuans at Hillswick. Ice has made distinct markings, running east and west on the gneissose rock close by the door of the farm-house of Ailesburgh, which is perhaps about a mile north of the narrow isthmus of Mavis-Grind. The huge moraine-looking mound, which lies between the south-east foot of Ronas-hill and the head of Ronas-voe, claims a special examination by those who wish to be further satisfied as to the former existence, or otherwise, of glacial action in Shetland.
