We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
The Goldfield Mining District, Nevada—Part II

A New Look at Old Mines
Exploration companies are actively looking for properties with profitable potential, even if the ground was once cast off as too low in grade to be economically viable. This is especially true in states that are reasonably friendly toward...
The Heavy Minerals in Your Concentrates
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
Silver and Base Metal Deposits of the Pioche District
The areas that were mineralized with the bedded ore were huge and vast tonnages were indicated, although they had no idea at the time.
