One possible route of such an expedition, connecting the Hudson Bay with Kensington, would lead up either Nelson River or Hayes River, through Lake Winnipeg, then up the Red River of the North. The northern waterway begins at Traverse Gap, on the other side of which is the source of the Minnesota River, which flows south to join the Mississippi River at Saint Paul/Minneapolis. This route was examined by Flom (1910), who found that explorers and traders had come from Hudson Bay to Minnesota by this route decades before the area was officially settled.
