Creeking: Prospecting or looking for gems, minerals or other treasures in a creek by using a screen.
Sluicing: Flowing water is used to wash away sediment to find gems, minerals or other treasures.
Screening: Loose dirt is shoveled onto a screen; the screen is then shaken to remove small particles, leaving larger chunks of earth, which can be examined for gems.
Picking: A pick ax can be used on the walls of a mine to reveal treasure hidden among loose rocks or within broken rocks.
