Abstract
SUMMARY: The drumlin‐like landforms that Tyrre'll described in 1896 as lrdrumlinoidstl are themost characteristic features of glacial origin in the Barren Grounds. Their widespread distribution throughout the glacial‐drift covered portions of this region, as well as manyother regions in more southerly lati‐tudes covered by glacial materials, implies that thedrumlinoids are a rather significant landform developed under a continental glaciation. A yet, the pro‐cesses involved in their formation can only be speculated upon, or at best, drumlinoids might be regarded as being related to drumlins and therefore formed in a similar manner. There are a number of glaciological and geomorphological factors apparently affecting theirformation. Some of these are discussed here, but, until more detailed investigations have been carried out especially in field surveys, and a definite classification of such features has been evolved, drumlinoids can only be definitely described as widespread features which re‐sulted frc TI both depositional and erosional processes of a continental ice sheetFurther study concerning the nature and orientations of the drumlfnoids in the BarrenGrounds, and elsewhere, dong with an investigation into the pro‐cesses involved En their origin should bring to light much useful Information. Such information would not only concern glacial geology and geomorphology, but also glaciology, and, indirectly, glacial climatology.
