Canadian Shield

Being a Canadian carries with it a tangible sense of living on the edge of a vast barren interior. Only named as such in 1883, the Canadian Shield is an empty immensity of lakes, bogs, rivers, forest and protruding ribs of hard Precambrian crystalline rock that covers more than half of the total land area of Canada. This book traces the geologic evolution of the Shield, its first tentative exploration by humans starting 11,000 years ago as the last great ice sheets withdrew, its changing economic fortunes as Europeans penetrated its remote rocky vastnesses for furs and metals, and its transformation in the twentieth century into a national icon to Canadians. Regarded as 'barren' and of no value, much of the Shield was given away in 1670 to a single London-based fur trading company, the Hudson Bay Company, who jealously guarded its northern domain until 1867. This two hundred year long monopoly created a virtual government over a huge piece of North America. Without the HBC, much of it would have passed into American hands and there would have been no 'Canadian' Shield or country called Canada. As a nation, we are indebted to hard rock.

Examines the history, geography, climate, plants, animals, and peoples of the Canadian Shield region of Canada.

More than 400 rock paintings adorn the Canadian Shield from Quebec, across Ontario and as far west as Saskatchewan. The pictographs are the legacy of the Algonkian-speaking Cree and Ojibway, whose roots may extend to the beginnings of human occupancy in the region almost 10,000 years ago. Archaeologist Grace Rajnovich spent fourteen years of field research uncovering a multitude of clues as to the meanings of the paintings. She has written a text which is unique in its ability to "see" the paintings from a traditional native viewpoint. Skilfully weaving the imagery, metaphors and traditions of the Cree and Ojibway, the author has recaptured the poetry and wisdom of an ancient culture. Chief Willie Wilson of the Rainy River Band considers Grace's work "innovative and original."

This volume, the third in a series on the Canadian Precambrian Shield presented by the Royal Society of Canada, was prepared by Fellows of the Geological Sciences Section, in response to their desire to bring up to date and to synthesize information available on the structures present in the Shield. It is a contribution to the basic understanding of the significant geological structures in the Canadian Shield. A knowledge of these features is valuable for long-range exploration and development of the extensive one deposits of gold, uranium, nickel, copper, lead, zinc, and other metals found in the Shield. It also has an importance in relations to oil structures found in rocks younger than the Precambrian, bordering the Shield. This work should be of great interest to those wishing to have a modern interpretation of Precambrian structures, especially the Canadian rocks, and to those concerned with the development of the Canadian North. It will be of special interest to practising geologists in government or industry, to university departments of geology, and to geological consultants.
