Eight miles long and four miles wide, Grand Island lies off the south shore of Lake Superior. It was once home to a sizable community of Chippewa Indians who lived in harmony with the land and with each other. Their tragic demise began early in the nineteenth century when their fellow tribesmen from the mainland goaded them into waging war against rival Sioux. The war party was decimated; only one young brave, Powers of the Air, lived to tell the story that celebrated the heroism of his band and formed the basis of the legend that survives today.
