This short text by Jean Maria Arrigo gives an overview of the successive waves of peoples who populated the Blood River tributary in the Amazon River Basin in pre historic -precolonial times. This brief review begins with the clan of Big Giant, who turned a boulder inside out to create his wife, and shook his family into existence from naked rock. It ends with the Camp People, the respected and valued hosts of the hungry slopes, who broke the chain of conquest, until Europeans Arrived.
