These samples were recovered from tenches along the East Canyon fault, a northeast-trending range-front fault generally bounding the northern side of the intermontane valley between East Canyon and Croyden in the Wasatch Range (Black and Hecker 1999). Botanic components and detrital charcoal were identified, and potentially...

A total of four bulk soil samples from the Dutchman Draw Trench site on the Washington Fault in northwest Arizona were examined to recover organic fragments suitable for radiocarbon analysis. These samples were recovered from soil stringers in the PE wedge, as well as from paleosol beneath the Most Recent Event (MRE) wedge in the North paleoseismic trench. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Two of the samples...

A total of six bulk soil samples from paleoseismic trenches were floated to recover organic fragments suitable for radiocarbon analysis. Three samples were recovered from the Bulnay Fault in northern Mongolia and from the San Andreas Fault in northern California. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A total of 11 AMS radiocarbon dates were obtained.

Three sediment samples from the Paradox Valley, Colorado, were floated to recover organic fragments suitable for radiocarbon analysis. Two botanic samples also were submitted for identification and radiocarbon dating. These samples were recovered from trenches for a geologic study to determine if the area contains active faults. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A total of four samples were processed for AMS...

Charcoal and bulk soil samples were examined for the Jedediah Smith Campground Project in Del Norte County, California. Nine charcoal samples were examined from prehistoric site CA-DNO-332. One charcoal sample and two bulk soil samples were recovered from a geomorphological area north of the site. Charcoal from the geomorphologic context will help date local landforms. Charcoal samples from CA-DNO-332 were identified to provide information concerning woods burned as fuel by the site...

Bulk soil and detrital charcoal were recovered from the Sand Flat site and from the Oak Tree site in the western Sierra foothills of California. These sites represent paleoflood study sites along the South Fork American and Middle Fork American Rivers. Botanic components of the bulk soil samples and detrital charcoal will be identified, and potentially radiocarbon datable material will be separated.

Bulk soil and detrital charcoal were recovered from sites in the Cantua Stream Group Paleoflood Study along the eastern flank of the Coast Ranges in the west-central San Joaquin Valley, California. These sites represent studies along Cantua Creek, Salt Creek, and Los Gatos Creek. Botanic components of the bulk soil samples and detrital charcoal will be identified, and potentially radiocarbon datable material will be separated.

A selection of bulk soil samples collected from trenches and augers excavated as part of the Rovner Simi Project, Simi Valley, southern California, were floated to recover organic fragments suitable for radiocarbon age determination. In addition, two charcoal samples also were submitted for identification and microscopic charcoal was extracted from five sediment samples. Botanic components and charcoal fragments were identified, and optimal radiocarbon datable material, including microcharcoal,...

A total of 29 samples from six sites along the lower Kern River near Lake Isabella,California, and six samples from two sites along the upper Kern River near Camp Nelson, California, were examined to recover organic fragments suitable for radiocarbon age determination. These samples were recovered from either fine-grained, sandy flood deposits or from weathering profiles developed in granitic grus on strath terraces cut into the bedrock in seven soil pits and a natural exposure. Botanic...

Two samples from a low terrace/alluvial fan along Clear Creek, a tributary to the Sacramento River in northern California, were floated to recover organic fragments suitable for radiocarbon analysis. These samples were collected from the Igo Bridge site for the Whiskey Town Dam project. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. A single charcoal sample was submitted for AMS radiocarbon analysis.

Bulk soil and detrital charcoal samples were recovered from natural exposures or soil pits on stream terraces adjacent to the Dungeness River in the northeastern portion of the Olympic Peninsula, Washington. These samples are from terraces incised into the alluvial plain between the eastern Olympic Mountains and the Strait of Juan de Fuca at Dungeness Bay. Botanic components and detrital charcoal were identified in each of the samples, and potentially radiocarbon datable material was separated.

A total of eleven bulk soil samples, three charcoal samples, and two shell samples were examined for the presence of organic material suitable for radiocarbon analysis. These samples were recovered from two trenches at the Penrose Drive site in Salt Lake City, Utah. Botanic components and detrital charcoal were identified, and potentially radiocarbon datable material was separated. Dating of material from the trenches will be used to help develop detailed information on the timing and recurrence...

Detrital charcoal samples from stream terrace deposits along the Little Colorado River, Arizona, were floated to recover organic fragments suitable for radiocarbon analysis. These samples were collected from natural exposures or soil pits as part of the Little Colorado River Sediment Transport Study. Botanic components and detrital charcoal were identified, and potentially datable material was separated.

A single bulk soil sample from the side of a shallow gully incised in the footwall of the Wasatch Fault, Levan segment, near Skinner Peaks, Utah, was floated to recover organic material suitable for radiocarbon analysis. Botanic components and charcoal were identified, and potentially radiocarbon datable material was separated. A single charcoal sample from this location also was submitted for identification prior to radiocarbon analysis.
