| Summary: | The importance of Labrador-Ungava as one of the main gathering grounds and centres of dispersal of the Laurentide ice sheet, and as the location of the final disappearance of the ice was recognized as early as 1896 with the publication of the reports of the government geologist, A.P. Low. Despite this knowledge the peninsula has received very little attention until recently, due undoubtedly to its inaccessibility, and to the practical difficulties of field research in the subarctic environment. Until about 1945 the studies of glacial geomorphology that had been completed ( with the exception of the early work of Low) were almost entirely confined to the coastal regions, in particular to the Atlantic coast of Labrador. The most significant scientific contribution was that of Tanner, who visited the coast of Labrador in 1937 and 1939. The investigations of Tanner and his colleagues, and Tanner (1944) synthesis of the reports of earlier geologists were published in a summary of the glaciations of the entire peninsula, which remains the standard regional reference to this day. Inevitably, with the meagre, and o:tten not entirely accurate information of the interior parts of Labrador Ungava there is a marked contrast in the degree to which detailed evidence is available to the glacial geomorphologist, attempting to decipher the details of glaciation over the whole peninsula.
