This is the most seaward and deepest portion of a basin floor fan. It is just down slope from the mid fan which in turn extends into the proximal fan, then the toe of slope channels and their associated coarser sediment (Beaubouef et al, 1999). Erosion from the canyons into the slope and the updip incision of fluvial valleys into the shelf feed the sediment that are spread out over the fan proper. This portion of the basin-floor fan has the most flattened surface and few if any channels. Traced seaward across the basin floor fan is the basin floor.
