Valentine has proposed that Ojibwe dialects are divided into three groups: a northern tier consisting of Severn Ojibwe and Algonquin; a southern tier consisting of "Odawa, Chippewa, Eastern Ojibwe, the Ojibwe of the Border Lakes region between Minnesota and Ontario, and Saulteaux; and third, a transitional zone between these two polar groups, in which there is a mixture of northern and southern features."
