Abstract
It is presumed that, at a time when so much is said about the conservation of Boulders, a number of personal observations on these interesting objects may not prove unacceptable to the Geological Society. Westmoreland .—The Shapfell boulders first claim our attention on account of their size, the very distinct character of their parent rock, and the fact of their having found their way into Yorkshire over a part of the Pcnnine Chain, 1500 feet above the sea-level. There is a kind of granite now quarried at Dalbeattie, on the west side of Criffell, which may occasionally be found in drift a great distance to the S.S.E. This granite contains large oblong brown crystals of felspar, and might easily be mistaken for Shapfelt granite by one not familiar with the latter; but in Westmoreland and Yorkshire there would be little chance of such a mistake occurring. The base and sides of Wasdale Crag (from which the granite boulders radiated) are more or less covered with very compact pinnel packed full of rounded and glaciated boulders of granite and dark metamorphic felstone. These boulders, however, are seldom very large. On the surface of the pinnel, and more or less associated with a thin covering of red loam and angular débris,there are many very large angular or subangular blocks. On walking from Shap to the Shap-summit Granite Works, I saw a block about 12 feet in average diameter, and was credibly informed that there was a block high up on the side ofThis publication has 0 references indexed in Scilit:
