88. Preliminary Geoarcheological Reconnaissance
in Badlands National Park, South Dakota.
Preliminary geoarcheological investigations were
conducted in Badlands National Park, South Dakota,
in August of 1997. The purpose of the research was to establish
an initial stratigraphic and geomorphic
context for archeological materials within the park. This was accomplished
by large-scale surface
reconnaissance and intensive data collection at a number of representative
study sections. The reconnaissance
focused on identifying major geomorphic landsurfaces extant in
the park area. These include: the
Upper Prairie surface and Badlands Wall; the Lower Prairie surface
and Sage Creek Basin; Pleistocene (?)
Cheyenne River Terraces; and the early Pleistocene/late Tertiary
(?) surface. Individual study sections
were located at representative examples of late Pleistocene and
Holocene sedimentary depositional environments
within each of the various landsurfaces. These included sod tables,
which are eroded and often
isolated bodies of reworked alluvial and colluvial sediments, alluvial
lag deposits, eolian loess mantles,
alluvial terraces, and alluvial fans. A preliminary geochronologic
framework for the various depositional
environments was provided by the procurement of conventional and
AMS radiocarbon age determinations.
These data, along with temporal/spatial information obtained from
existing archeological site records,
were used to develop general predictive statements about archeological
and geological relationships
in the park area.
