 Palliser found that the entire region was suitable for agriculture, except for one semi-arid region that became known as the Palliser Triangle.Up until 1870, the region was nominally under the control of the Hudson’s Bay Company, although there was essentially no law enforcement.In 1873 a skirmish between white and Métis traders and members of the Assiniboine First Nation, which came to be known as the Cypress Hills Massacre, prompted Prime Minister John A. Macdonald to create the North-West Mounted Police.
