Maryann Luke was a great geologist, although she never made the great find that would launch one to the top of her field. She was ultimately committed to the research of indigenous tribes of people in Africa.Her documentation was outstanding yet she couldn't have prepared forher stay with the Ouctawie people. When Maryann arrived they weren't too much different from the surrounding tribes in the country. Save for the large crater that was in the middle of their settlement.
