A Study of Glacial Geomorphology in the Northern Torngat Mountains, Labrador
This study was begun in 1959 and continued during the field season of 1960, when my wife Inger-Marie acted as assistant and we spent a little over 9 weeks in the field from early July to mid-September. Base camp was set up at the northern end of Eclipse Channel and from there several journeys of 3-...
