A single bulk soil sample was recovered from a paleoseismic study trench in San Francisco Bay, California. Botanic components and detrital charcoal in the sample were identified, where possible, and potentially radiocarbon datable material was separated. Radiocarbon dating of the detrital charcoal present in the sample will aid in interpretation of the timing of the most recent earthquake along the San Gregoria fault.
