This is the only book to focus 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. 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
Professor Norm Catto joined Memorial University in July 1989. His research and teaching interests include coastal landforms, natural hazards, sea level change, and impacts in coastal environments; response of river systems to climate and weather events, and flood risk assessment; aeolian geomorphology and response to climate and human factors in boreal and costal environments; mass movements and slope failures; loess deposition; palaeosol formation; emergency measures policies and effectiveness human adaptations to climate and weather events; the impacts of climate and weather events on agriculture, transportation, fisheries, and communities; and the relationships among landscapes and people. His research has included projects and investigations in landscapes and environments in 16 countries, and in all Canadian provinces and territories, particularly in eastern Canada. For 18 years, he served as Editor-in-Chief for Quaternary International, a professional international journal dedicated to the study of landscape evolution and climate variation
