The North Saskatchewan River stretches across the Canadian provinces of Alberta and Saskatchewan. It flows out of the ice fields in the Rocky Mountains, down through the foothills and across the prairies.On most of it’s east – west journey it seperates the great western plains to the south from the boreal forests of the Canadian north. This unusual geographical position allows it to shelter a wide diversity of plants and wildlife, some of the speecies at the southern end of their natural range and some species at the northern end.
