Use this picture as a very crude map to fortune. Within the top most circle is a downed tree where in its bark or cracks, you might find gold dust. In the second circle is a mini sand bar. This shallow water is useful in slowing down traveling gold so check this kind of area closely. Third and last circle is a rocky area. These rocks slow down the heavier sand or dirt where you'll find gold the easiest. Throw some rocks around and dig underneath for your best chance to find bigger portions of gold. Obviously, you're not likely to find gold in living trees.
