On June 25, 1913, Chief Joseph Bighead, representing Big Island Lake Cree Nation, also known as Lac Des Isles, signed an adhesion to Treaty 6. Indian Agentsgot into the habit of referring to Big Island Lake as Joseph Bighead’s Band. The name stuck until 2000 when Indian Affairs was reminded to call the Band Big Island Lake Band by its original name of Big Island Lake Cree Nation and its Territory as signed at Treaty Adhesion. Chief Joseph Bighead – Atinistikwan chose not to follow anyone. He and his Band remained independent of any Tribal Council or Federation, in the belief that membership serves to diminish Treaty Rights.
