XV. Notes on Glacial Mounds near Balquhidder, Perthshire

Abstract

In this Paper the author described some remarkable glacial mounds which occur in the neighbourhood of Balquhidder, Perthshire. They had attracted his attention when passing through the district several years ago, and more recently he had had an opportunity of looking at them again. The locality, as the members were aware, is on the line of railway between Callander and Killin. Proceeding from the Bridge of Allan to Callander, we cross the great belt of the old red sandstone of Scotland, deeply covered in many places with till and “upper drift,” and strewn here and there with erratics, some of considerable size. Near Callander we come upon the conglomerate at the base of the system, which extends north-east by Crieff and Dunkeld, and south-west by Aberfoyle, and through Loch Lomond to the Firth of Clyde. Here we observe some well-marked instances of striation. Leaving Callander, we enter the schistose region at the Pass of Leny; and as we pass along the shores of Loch Lubnaig, we see striking examples of ice-work on the hill sides and along the bottom of the valley. From Callander our course has been nearly due north, but at Kingshouse the upper part of Strathyre bends sharply round to the west, extending about two miles in that direction to Balquhidder, at the foot of Loch Voil. This beautiful, lonely lake stretches some four or five miles further west towards the lofty range of mountains, several of them about 3000 feet in height, which forms the watershed
