- Comments
- EgPm-179, Hawkwood: These uplands consist of severely pocked hummocky moraine, and the site consists of stratified deposits in two basins. The eastern basin contains five components representing occupations 1 and 3-6. The western basin contains only three components, representing occupations 2 and 5-6. Occupation 1 is a late Palaeoindian manifestation of the Plains Mountain tradition. Occupations 2 and 3 are early in the Mummy Cave series, while occupation 4 is a late Mummy Cave component with Bitterroot points (actually closer to Walker's [1992] Gowen type, being short with slightly convex blade edges and with notches very close to a straight or barely concave base). Occupations 5 and 6 represent Oxbow and Old Women's components, respectively.
