Copper Canyon's alluvial fan is often used in illustrations because of
its near perfect symmetry and limited extent. The fan shows a radial drainage
pattern extending outward from its sediment source (Copper Canyon in the
Black Mountains) and shows gradation form coarser, dark alluvial sediments
high on the fan that grade to finer, light colored sediments in trunk
stream channels that run along the toe of the fan. Click here for a zoomed-in view of the fan. Scale (1:48,000); north is to the left. [Note: Hit the "back" key to return to the previous tour image.] |
