Hummocky Moraine Drift

Abstract

DURING his survey of the West Pacific slopes, Clarence King found and has since described, hummocks of moraine drift on the “dying-out glaciers,” which are somewhat similar to the “hog-wallows;” and J. le Conte has described dying out glaciers and moraine drifts of California. Abstracts of these descriptions will be found in the American Journal of Science and Arts, and the full description of the West Pacific slopes in Clarence King's report. In West Galway, Ireland, there are in places large tracts of drift sometimes like Clarence King's description, in others like the “hog-wallow;” that in the Memoirs of the Irish branch of the Geological Survey have been described as “rocky moraine drift.” The accompanying sketch is of some of these drift hummocks on the north slope of Croagh-na-Cloosh, south of Oughterard.
