Figure F2. Depth-converted seismic section CR-20, crossing Sites 1039, 1040, 1041, and 1043. Processing and depth conversion are by K.D. McIntosh, based on seismic velocities from Christeson et al. (1999). Heavy lines are interpreted unit boundaries or faults. Most faults upslope from the frontal thrust outcrop are out-of-sequence thrusts. These later faults cut the prism, the slope apron, the deformed wedge, and even the underthrust sediments.
