Geosphere, October 2015, v. 11, p. 1629-1650, doi:10.1130/GES01123.1, Supplemental Figure S5 - (A) East wall of sample pit DR-14. This pit is excavated on the upthrown side of the Ventura fault along the Day Road transect 20 m north of CPT-3. Locations of luminescence samples are shown with yellow circles. Orange circle highlights location of charcoal sample DR14-CL01 from a depth of 126 cm. Oblique black box shows projection of image in B. Red line marks discrete contact between silty sand unit and the slightly darker clay horizon below. (B) Close-up of sample locations. Orange circle shows location of charcoal sample DR14-CL01. The sedimentary layers above the charcoal sample do not appear to be bioturbated.
