Pollen analysis was undertaken at 48SW1242, 4b, in connection with archaeological mitigation. This site is located at an elevation of 6450 ft in the Shute Creek Drainage Basin at the extreme western edge of Sweetwater County. Three components were recorded at the site. The later two components range in age from 1550 to 2170 B.P. Two stratigraphic columns, which combine to represent the entire period of occupation, were sampled for pollen to assess the paleoenvironment. In addition, samples...

Site 48SW7095 is a short-term prehistoric camp located along raised sandy deposits overlooking Laundry Draw in Sweetwater County, Wyoming. Occupational evidence is visible on the surface, although silty deposits on the lower drainage terraces contain some buried cultural materials (John Greer, personal communication June 15, 2015). Ashy fill from cores into the center of two hearths were submitted for macrofloral analysis and AMS radiocarbon age determination. Samples are expected to range from...

Samples from features at sites 48SW11405, 48SW16982, 48SW16986, and 48SW16988 in Sweetwater County, Wyoming, were floated to recover macrofloral remains. These sites were excavated as part of the NRG Questar Wamsutter Expansion project, and represent prehistoric open camps. Macrofloral analysis is used to provide information concerning plant resources utilized by the various occupants of these sites.

Fill and fire-cracked rock recovered from six hearths at the Sevenmile Gulch Site (48SW1673) in Sweetwater County, Wyoming, were submitted for organic residue analysis. Samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis is used to gain information regarding economic use of plants and animals at the site, and perhaps feature and artifact function.

Fill and fire-modified sandstone from three hearths at site 48SW17323, a prehistoric camp, located in the central portion of the Greater Green River basin in Sweetwater County, Wyoming was submitted for organic residue analysis. Samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis provides information concerning the compounds that were extracted from the fill and fire-modified rock samples and through matches with our reference...

Charcoal from the fill of a basin-shaped hearth at the Elbee Village site (32ME408) was submitted for identification. This hearth was exposed in an erosional cutbank of the Knife River and contained an abundance of charcoal. The Elbee site is an extensive earthlodge village in west-central North Dakota dating to the A.D. 1500s. The hearth was found away from and stratigraphically below the level of the village and might reflect an earlier occupation of the area.

Fill and sandstone slabs from four hearths at site 48SW7456, a prehistoric camp, located in the central portion of the Greater Green River basin in Sweetwater County, Wyoming were submitted for organic residue analysis. Samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis provides information concerning the compounds that were extracted from the fill and sandstone slabs and through matches with our reference library of raw and...

A total of 14 sediment samples and feature fill samples were submitted for phytolith and starch grain analysis from an Archaic Period campsite located in Sweetwater County, Wyoming. Samples consisted of controls collected from around the site and from various types of intramural features excavated into room floors. This analysis was undertaken to better understand feature function and some of the plant resources utilized by the site occupants.

Site 48SW13143 (18-WAS-008) is located on the southeastern slope of a northeast/southwest-trending low ridge complex in the Washakie Basin of Sweetwater County, Wyoming. During data recovery excavation in connection with the Mountain Gas Resources Caprock 1599-23-41H Pipeline Evaluative Testing, three sub-surface basin hearth features, including Features 1 and 3, were discovered within an area (ca. 8 x 6 m) containing four previously recorded, scattered hearth features and a possible ash dump...

Site 48SW3006, located in southwestern Wyoming south of the Chain Lakes Rim and north of Wamsutter, represents multiple hunter-gatherer open camp fire pits. Ten thermal basins were selected for pollen analysis. Radiocarbon dates for these features range from 5430 ± 30 BP to 1090 ± 30 BP. Two stratigraphic samples and a modern surface sample complete the pollen record for this site.

Site 48SW17760, located in Sweetwater County, Wyoming, documents a prehistoric camp on the east side of a low hill that occupies the eastern side of an interfluvial ridge in the northeastern portion of the Washakie Basin (Matthew Kautzman, personal communication May 4, 2015). Open trench inspection of 2010 pipeline construction and subsequent auger, shovel, and test units identified features and artifacts, dated to 1280 ± 40 BP, or the Uinta Phase (Matthew Kautzman, personal communication May...

The Sourdough I Site (48SW19463) is located 20 miles north of Wamsutter, Wyoming, in the northern portion of the Great Divide Basin. The site is situated on a land peninsula, extending into a dry playa lake bed. Site 48SW19463 exhibits seven features, four of which were sampled for pollen, starch, and/or FTIR analysis. Features 1 and 2 date between 1680–1730 BP, indicating an early occupation phase of the Late Prehistoric Uinta Phase. Features 4 and 5 date between 1070–1120 BP, indicating a more...

Site 48SW16962, situated south-southwest of Wamsutter, Wyoming, is an open lithic scatter comprised of three cultural features (Features 1, 2, and 3) representing an Uinta Phase occupation. Sediment samples from each feature were submitted for starch analysis to identify starchy foods cooked in these features.

Sediment samples from the fill of a basin house and associated features at site 48SW16996 in Sweetwater County, Wyoming, were submitted for starch analysis. Fire-cracked rock from fill of a hearth within the basin house also was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Radiocarbon dates suggest that the house dates to the Opal phase of the Early Archaic. Starch and organic residue (FTIR) analyses will be used to provide information concerning plant...
