Surficial Geology And Geomorphology Of The Western Olympus Range, Antarctica: Implications For Ice-Sheet History, Brett Vandenheuvel
Surficial Geology And Geomorphology Of The Western Olympus Range, Antarctica: Implications For Ice-Sheet History, Brett Vandenheuvel
Electronic Theses and Dissertations
A widespread erosion surface passes across bedrock and sedimentary deposits in the western Dry Valleys sector of the Transantarctic Mountains (TAM), southern Victoria Land, Antarctica. The surface includes stoss-and-lee slopes, channels, potholes, scoured basins, and corrugated bedrock. These features have been taken to represent subglacial meltwater erosion beneath a greatly expanded East Antarctic Ice Sheet (EAIS) in the mid-Miocene (Denton et al. 1984, Marchant et al. 1993a). Sedimentary deposits that are typically associated with ice-sheet wastage, such as outwash, are not present on the erosion surface. The lack of these deposits indicates that the expanded ice-sheet postulated to be responsible …

Late Maritime Woodland (Ceramic) And Paleoindian End Scrapers: Stone Tool Technology, Pamela J. Dickinson
Electronic Theses and Dissertations
Archaeologists tend to view lithic assemblages from a predominately morphological perspective, stressing the importance of the fluted point as the defining characteristic of the Paleoindian culture period (ca. 10,000 years B.P.). In applying such a characteristic, Paleoindian sites have been identified throughout the Northeast. However, there are no identified Paleoindian sites in New Brunswick. It is possible that some sites are largely ignored or thought to lack a Paleoindian component if a fluted point is absent. If such sites are being overlooked, then the database may under represent the Paleoindian culture period. Spurred end scrapers commonly occur in known Paleoindian …
