A alluvial gold sluice box is an artificial channel into which gold-bearing gravel are flushed. With enough water to wash away all the large boulders that have been screened, the gold settles to the bottom of the water, where it is captured by slats called "riffles". The riffles act as tiny restrictions to the water's flow, creating low ...
