Wave action along the Lima Reservoir in Centennial Valley, Montana has exposed three adjacent Paleoindian sites along the north shore cutbank. While these sites date to the same period and are near each other (within 1.5 miles), they possess markedly different geologic contexts. The westernmost site, 24BE43, is a surface scatter resting on an old soil with a very well-developed Btk horizon. The eastern site, 24BE52, is also a surface manifestation but it sits on a very thin soil capping what...
The Geoarchaeology of Late Prehistoric Irrigation in Central Utah (2015)
In 1928, Harvard archaeologist Noel Morss observed ancient irrigation systems in central Utah during fieldwork that first defined the Fremont culture. Instances of Fremont irrigation are known, but perceptions of the Fremont as a small-scale society of indigenous mixed foragers and farmers delayed empirical evaluation of Morss’s report. Fieldwork, beginning in 2010 and continuing, now identifies a complete irrigation system 4.5 miles long bringing water from 8,500’ to a 90-acre field at 7,100’...
OSL Dating at the Wakulla Springs Site (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The Wakulla Springs site is a well-known paleoindian site in Florida, which contains abundant Pleistocene megafauna and artifacts including early projectile points. Previous optically stimulated luminescence (OSL) dating at the Wakulla Springs Lodge site (8WA329) suggested occupation older than 11.6 ka but younger than 22.5 ka (W.J. Rink et al. Florida...
Refinement of the Chronostratigraphy and Age of Pit Features at the Cooper's Ferry Site, Idaho (2017)
The Cooper’s Ferry site, which is located on an alluvial terrace at the confluence of Rock Creek and the Salmon River in Idaho, contains a stratified sequence of Western Stemmed Tradition archaeological components within alluvial and aeolian sediments. Excavations have revealed large quantities of lithic artifacts and numerous cultural features, including several storage pits. Recent excavations have encountered artifacts and faunal materials from intact deposits located beneath the late...
Understanding Archaeology in the Dunes: OSL Dating of the Tolleston Beach at Indiana Dunes National Lakeshore and Its Implications for Interpreting the Archaeological Record (2019)
This is an abstract from the "SAA 2019: General Sessions" session, at the 84th annual meeting of the Society for American Archaeology. The puzzling scarcity of archaeological sites on the Tolleston Beach at Indiana Dunes National Lakeshore prompted an investigation into the development of this dune field in an attempt to determine whether the distribution of known archaeological sites is governed by ancient human behaviors, or influenced by its dune setting, which can affect site preservation...
