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 mine site consists of river gravels from an ancient channel covering over 20 acres, and the place is covered with very large river rock and small tree overgrowth.
Some gems can potentially poison you, make you sterile and even make you forget who you are.
In underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
