Sediment samples were collected from the Jacks Valley Trench and the Peavine Trench across active normal faults in Nevada with the purpose of gaining insight into earthquake activity. These sediment samples were examined to recover organic material suitable for AMS radiocarbon dating. Several types of charred macrofloral remains were noted in the Jacks Valley Trench sample. No macroscopic charcoal or other organic fragments were noted in the Peavine Trench sample; therefore, it was processed to...

Fill from a hearth fragment at the Rockshelter Ridge site (41BS1533) in Brewster County, Texas, was floated to recover charcoal for radiocarbon dating. This hearth fragment was eroding out of the side of a gully. The site consists of a series of 14 rockshelters, and artifacts from the site date from possibly as early as 6,000 BP to approximately 500 years BP. Charcoal from the hearth was processed for AMS radiocarbon dating.

Samples were examined from 11 stone ring sites in the Coteau Mine Area in Mercer County, west-central North Dakota, to provide subsistence information. These sites will be impacted by expansion of coal strip mining operations. A total of 33 lithic tools from these 11 sites were analyzed for possible protein residues to determine animal resources that might have been hunted/processed with the tools. Five fill samples from hearths associated with stone rings at sites 32ME169, 32ME755,...
