    desert dry washing for gold nuggets and how to prospect

    Winnowing was the original dry placer method. This process involves screening out all the coarse gravel, placing the fines in a blanket and tossing them in the air, preferably in a good wind. The lighter particles are blown away by the wind and the heavier, usually more valuable minerals fall back onto the blanket
