Figure 1. A.) This photograph shows fan deposition on the side of a river. The sediment from this depositional event will most likely be washed away rather than preserved in the stratigraphic record.
B.) This photograph shows alluvial fan deposition onto a stable river terrace plateau where it has been retained and preserved. The two alluvial fans shown will continue to accumulate sediment from future hillslope runoff events, which will appear as layers in the fan stratigraphy.
