Book Description
The study was prompted by a need for data on terrain conditions, soil materials, and glacial transport, which was required for mineral exploration, for the planning of a hydroelectric transmission corridor, for bedrock mapping, for forest inventory, and for land capability studies. A secondary reason for beginning a program of surficial mapping in this part of Newfoundland was the paucity of Quaternary geological information in a key area about which early reports debated the extent of glaciation, and where airphoto reconnaissance revealed significant new glacial and marine formations.

Book Description
This book is the second of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimate modelling. In order to provide the information for the widest-possible range of users in the most accessible form, a series of digital maps was prepared.The glacial limits were mapped in ArcView, the Geographical Information System (GIS) used by the work group. Included with the publication is a CD with digital maps, showing glacial limits, end moraines, ice-dammed lakes, glacier-induced drainage diversions and the locations of key sections through which the glacial limits are defined and dated. The last deglaciation is also shown in 500 year time-steps. The digital maps in this volume cover the USA and Canada and include Greenland and Hawaii. Both overview maps and more detailed maps at a scale 1: 1,000,000 are provided.Also available:Part I: Europe, ISBN 0-444-51462-7Part III: South America, Asia, Africa, Australia, Antarctica, ISBN 0-444-51593-3

Book Description
This critical book focuses on the geomorphological landscapes of eastern Canada and provides a companion volume to “Landscapes and Landforms of Western Canada” (2017). There are a number of unique characteristics of eastern Canada’s landscapes, notably its magnificent coastlines, the extraordinary variety and extent of wetlands, the huge Great Lakes-St. Lawrence basin, the high incidence of meteorite craters, the spectacular Niagara Falls, urban karst in Montreal and Ottawa, youthful, glaciated karst in Ontario, Newfoundland, Quebec and Nova Scotia, the ubiquitous permafrost terrain of Nunavut, Labrador and northern Quebec and the magnificent arctic fjords and glaciers. Looking at coastlines, the tidal extremes of the Bay of Fundy are world renowned; the structural complexity of the island of Newfoundland is less well known, but produces an astounding variety of coastlines in close succession; the arctic fjordlands of Baffin and Ellesmere islands and the extravagant raised beaches of Hudson Bay bear comparison with the classic fjords of Norway and the Baltic Sea raised beaches. As for wetlands, there are distinctive Arctic, Subarctic, Boreal, Eastern Temperate and Atlantic wetlands, and their extent is second only to those of Russia. In the Hudson and James Bay regions, between 75-100% of the terrestrial surface is comprised of wetlands. One of North America’s largest river basins, the Great Lakes-St. Lawrence basin, has its source in Minnesota, straddles the USA-Canada border and debouches into Quebec as the St. Lawrence River and evolves through its estuary into the Gulf of St. Lawrence, a journey of almost 5,000 km. As far as meteorite craters are concerned, 10% of the world’s total are located in eastern Canada, including some of the largest and most complex landforms. They are preserved preferentially in the ancient Shield terrain of Quebec. Finally, the three million km2 of permafrost controlled relief in eastern Canada serves as a reminder of the vulnerability of eastern Canada’s landscapes to climate change. Effects of warming are expressed through thawing of the permafrost, disruption of transportation corridors and urban construction problems, ever-present geomorphic hazards.

Book Description
This synthesis of the Quaternary geology of Canada and Greenland covers the regional Quaternary geology of Canada, applied Quaternary geology in Canada (including its influence on man's environment), the Quaternary geology of the ice-free areas of Greenland, and the dynamic and climatic history of the Greenland ice-sheet.

Book Description
List presenting 380 radiocarbon age determinations made on geological samples from Newfoundland, Nova Scotia, New Brunswick, Quebec, Ontario, Manitoba, British Columbia, Yukon Territories, mainland, Northwest Territories, Arctic Archipelago, and Washington. Archaelogical samples were taken from Newfoundland, Labrador, Nova Scotia, Ontario, and Northwest Territories, and Arctic Archipelago. A description of each sample is given, with its location and age.
