Geologic Journey

Geologists search for clues of massive tectonic shifts that reverberate through the continent, forcing the mountains up out of the plains. Bends and cracks reveal the growth pangs of the mountain building era.

This episode tells the story of the changes in the geology and landscape of the vast central area of North America. In recent geologic history, five interconnected freshwater lakes are formed. We explore a long vanished mountain range, the remains of a tropical salt-water sea and trace the story ...

Geologic time has shaped the Canadian Shield into a complex ensemble ranging over millions of square kilometres. The geography of the Shield has been surveyed from North to South, and yet its underground world still leaves much to be explored. The Canadian Shield is one of the last frontiers of h...

This episode tells the story in three dramatic chapters of how tectonic upheaval pummelled and pounded eastern North America until the shape we recognize today finally emerged. The discovery of fossils provides proof of how North America and Africa were once bound together. Tectonic movement lies...

From studying the sediment deposits at Anticosti Island, to rebuilding the history of one of the most significant mass extinctions (443 million years ago), scientists are piecing together elements that continue to shape this diverse region. Scientists reveal the fractures in this active earthquak...
