MASKI PITON, or Broken Arm, is perhaps the best-known or best publicised Cree Indian Chief, and has had more written about him than any other Chief or historic aboriginal person in Alberta. In spite of this, virtually nothing has been written about - or is known about - his band of the Plains Cree. Much that is known and has been written about him is incomplete and woefully lacking, not having been satisfactorily researched. In fact, the band ranged through a large area from the mountains of the North Saskatchewan to northern Minnesota. In fact, as it turns out, MASKI PITON's band is one of the best documented of the Plains Cree bands and, once we combine the records from Canada and the Untied States, we are able to reconstruct a very accurate record of the history of the band. This is the history of the Band from it's early origins to the reservation period, and is the first documentation of the range of the Plains Cree bands.
