Oswald "White Bear" Fredericks, a Hopi indigenous elder who was the main consultant for Frank Waters' Book of Hopi, explained Hopi history, which spans far back into past ages; he details the migrations of the Hopis' antecedents, which took them from a sinking Kasskara in the Pacific Ocean to Easter Island and on to South America, Yucatan, and Mexico, finally to what's now the United States. White Bear explains the basic Hopi world view and belief system to us in the domineering culture.
