It avoided the near approaches to the Iroquois Indian limits and led directly to the numerous Indian haunts around the greater lakes. As the objective point for the westward expeditions was gradually moved farther south into the Mississippi basin, shorter routes across the territory, later known as the Old Northwest, were used.
