Figure F1. Incoming sediment sections offshore Guatemala (Site 495) and Costa Rica (Site 1039). The incoming sediment section at Site 1039 is repeated beneath the décollement at Sites 1043 and 1040 arcward of the trench at Costa Rica, suggesting there is no sediment accretion at the toe of the wedge at present (from Morris, Villinger, Klaus, et al., 2003). Stratigraphic column at Site 1253 is nearly identical to that of Site 1039.
