Every March between 1826 and 1854, the York Factory Express began its journey from the Hudson's Bay Company's headquarters on the Pacific Ocean. From Fort Vancouver, the express-men paddled their boats up the Columbia River to the base of the Rocky Mountains at Boat Encampment, a thousand miles to the east. At Jasper's House they were 3,000 feet above sea level. Their river route would return them to salt water once more, at York Factory, on the shores of Hudson Bay. It was an amazing climb and an amazing descent, and they would do another climb and descent on their journey home. The stories of the York Factory Express, and of the Saskatchewan Brigades they joined at Edmonton House, are told in the words of the Scottish traders and clerks who wrote the journals. However, the men who made the journey possible are the invisible, unnamed Canadiens, Orkney-men, Iroquois, and their Métis children and grand-children, who powered the boats across the continent every year. The voyageurs did all the heavy work and were almost entirely responsible for the success of the 5,400-mile journey. But their history was oral. If the traders had not preserved the stories the voyageurs told them, we would not know this history today.
