Yakima River (Geographic Keyword)
1-2 (2 Records)
A total of eighteen charcoal samples and four bulk soil samples from soil pits or trenches on stream terraces adjacent to the Yakima River in eastern Washington were floated to recover organic fragments suitable for radiocarbon analysis. These samples were collected for a study of Holocene terrace chronology along the Yakima River. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Six radiocarbon dates were obtained.
RECOVERY OF POTENTIAL RADIOCARBON DATEABLE MATERIAL FROM THE BURBANK FAULT TRENCHES, KITTITAS COUNTY, WASHINGTON (2016)
The Burbank Fault Trenches are located east of Yakima River in Kittitas County, Washington (Scott E. K. Bennett, personal communication September 16, 2016). The light fractions of 11 bulk soil samples collected from units in two trenches (1 and 2) were submitted for macrofloral analysis to recover and identify material appropriate for AMS radiocarbon age determination.
