Collecting gold is fun! A sluice is a long, variably sized box, typically of wood or metal, gently inclined less than 20 degrees, where running water can wash significant quantities of gravel quickly. Gold and other heavy minerals, as described above, are retained in a series of riffles conventionally arranged along the floor of the sluice.
