Well-known
Yeah, there is scant history. Natives of interior BC, E. Washington & N. Idaho are connected by a river system and a language called Interior Salish. We are the salmon people because we had much of the riverbeds for salmon spawning (unlike the Atlantic salmon, Pacific salmon only return once to their original stream bed, to spawn and die).I have no idea where and if that line continues north into Canada.
Our boundary was from mid interior BC, south to Nez Perce lands; east to the Flathead tribe in Montana and west to the Yakama tribe.
