资源简介：
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 did not yield sufficient
macroscopic charcoal for dating; therefore, they were processed to recover microscopic
charcoal to obtain a radiocarbon date.
