These were nomadic peoples, who followed game, particularly the bison (or American buffalo) throughout the seasons. Their hunting grounds extended through Montana to the Missouri River, eastward along the Cypress Hills and northwards as far as the Wetaskiwin area. Everything to the north and east of this was considered the territory of the Cree – indeed, after the Riel Rebellion, when Mekastino (also called Red Crow), chief of the Blood First Nation, and Crowfoot, chief of the Siksika, were taken on a trip to Ottawa, they were familiar with the country as far east as Swift Current, but after that were out of their element.
