Unistai-poka (White Buffalo-calf) died at Washington in 1903. He was then almost eighty years of age, and had been the chief of his tribe for about a generation. In 1855, being then known as Feather, he signed the treaty negotiated by Governor Stevens. As a warrior, White Calf was famous among the tribes, but with the passing of inter tribal warfare he devoted himself to working in peaceful ways for the good of his people. He was remarkable in the breadth of his judgement, and in the readiness with which he recognized, and adapted himself to, the changes which his people were obliged to face when the buffalo vanished. Kindly, benevolent, and gentle of nature, White Calf yet possessed a sturdy determination and independence that bullying and threats could not move. Yet if reasons were advanced which appealed to his judgement, he was quick to acknowledge error and to modify his views – George Bird Grinnell..
