Geological History of Manitoba in posters

The geological history of Manitoba has been a real long one; it lasted almost 4 billion years! To get a glimpse of what Manitoba looked like in the long geological past I have compiled known information from various sources including my own observations into a series of six pictorial maps. Each map depicts what was happening in Manitoba during a particular period of time in the past. You will witness tremendous changes that have taken place in the geological past; from a deep ocean with occasional volcanic islands here and there into collisions of continents culminating into majestic chains of mountains that covered the whole province and far beyond. Later on, the mountains stopped growing and there followed a very long period of erosion that destroyed all but their deep roots that are now up to some 600 m above sea level. Part of the province was even under water during the age of the dinosaurs, then partly dried or withdrew as some of the water became ice on permanent glaciers elsewhere on earth. Finally, during the last 2 million years Manitoba was covered by glaciers until about 10,000 years ago.

A predicted rise of about 50 – 60 m in the sea level over the next few decades will change little the topography of Manitoba with the exception of the land aroundHudson Bay which will be submerged by the rising ocean waters.
