Eleven bulk soil samples and a single charcoal sample from the Wilcox Site on the Portland Hills Fault in Portland, Oregon, were submitted to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from soil developed on Missoula flood deposits. Two of the bulk sediment samples most likely to contain organic material were floated to determine if datable material was present in these samples. Because these two samples did not contain datable organic...

Four bulk soil samples from the Baca Lane Pit site (BA-MM04-25) in Alamosa County, Colorado, were floated to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from multiple buried A soil horizons within an eolian sand dune complex. Cultural (Holocene) artifacts are associated with several of the A horizons, and a small hearth with burned bird bones was noted. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable...

Two soil samples initially were floated to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from the Frenchman Mountain fault on the east side of Las Vegas, Nevada. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Charcoal from sample WMRFMF-04 was submitted to Beta Analytic, Inc., for the AMS radiocarbon analysis using the "MicroSample AMS Counting Service" now available; however,...

A total of three bulk soil samples from the Honey Lake Fault near the town of Doyle in northeastern California were floated to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from a distinct stratigraphic layer of a stream cut exposure during a paleoseismic study. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated.

Seven bulk soil samples from the Surprise Valley of northeastern California were floated to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from trench and stream exposures across a fault scarp in latest Quaternary lacustrine, colluvial, and debris-flow sediments. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated.
