11,500 to 10,500 years ago: Pleistocene Big Game Hunters
The Qu’Appelle Valley region was free of ice. Glacial lakes had formed in the northern areas, and spruce forests covered the region.
Following the retreat of the glacier, warming changes occurred and human evolution accelerated. People began to inhabit what is now southern Saskatchewan.
It is believed that people of this period may have traveled through the Qu’Appelle Valley rim, spear hunting big game animals such as the mammoth, camel, horse, ground sloth, and giant bison.
