The Ebeling Sotzmann Map of 1796
Note the name of the Wantastekw (today’s West River) in the center area: as Wantustitguck od West R. This is a very close rendering of the Sokoki Abenaki place referrent “Wantastegok” which persists to the present, in language as well as spirit (as they are of the same breath). See original here.
