Natural History
The history of this plains area actually began 2,000–2,100 million years ago wherein there were two continents separated by an ocean. The "Churchill Continent" which would be Manitoba and Saskatchewan, and the "Superior Continent" which would comprise Manitoba and Ontario. 1,830 – 1,800 million years ago these two land masses collided. The Northern shield area and western Rockies formed higher land from the collision.
The lower lands of today's parkland were covered by a shallow sea even in the Palaeozoic Era. It was not until the Cretaceous Period 144 – 65 million years ago that the inland sea began to drain. Here we begin to find the paleontological artifacts of various dinosaur species. The ice age of the Quaternary Period totally again re-shaped and re-shifted the landscape of Saskatchewan, occurring 2 million years ago.
Following these geological changes to this area, and the formation of the continent of North America as we know it, pre-history to the history of contemporary day can begin.

Famous quotes containing the words natural and/or history:
“I pity the men whose natural pleasures are burthens, and who fly from joy ... as if it was really an evil in itself.... Poor unfortunate creature that he is! as if the causes of anguish in the heart were not enowbut he must fill up the measure, with those of caprice; and not only walk in a vain shadow,but disquiet himself in vain too.”
—Laurence Sterne (17131768)
“A great proportion of the inhabitants of the Cape are always thus abroad about their teaming on some ocean highway or other, and the history of one of their ordinary trips would cast the Argonautic expedition into the shade.”
—Henry David Thoreau (18171862)
