EXAMINATION OF BULK SOIL AND DETRITAL CHARCOAL FOR RADIOCARBON DATABLE MATERIAL AND EXTRACTION OF MICROCHARCOAL FROM THE PENROSE DRIVE TRENCH SITE, EAST BENCH FAULT, SALT LAKE CITY, UTAH

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 of paleoearthquakes on the Salt Lake City segment of the Wasatch Fault zone. Samples for AMS radiocarbon dating will be submitted to Woods Hole Institute.
