Where To Find Gold In Rivers & Creeks : Complete Guide
Sudden dropoffs into deep water can act as great gold traps, and if you find one in a gold-bearing river, there is a great chance that gold has concentrated nearby. A dropoff works just like any of the other gold traps; as the water runs into the dropoff, the volume of the river suddenly expands massively, acting as a brake on the current.
