Travel northeast of San Domingo district's Hassayampa River to townships 6S and 7S, Range 4W in the Wickenburg Mountains. For the layman, take Grand Avenue or I-60 northwest out of Phoenix to Morristown (27 miles). San Domingo Wash is just shy of nine miles northeast of Morristown (see Resources).
Scour the San Domingo Wash, nearby washes and tributaries as well as hilltops and slopes to find much of the district's gold placers. Washes are arroyo or canyon areas that are streambeds fed with intermittent rainfall. Red Picacho's 7.5 minute quadrangles (1:24,000 scale topographic maps) pinpoint the county's most productive placer deposits.
Pan for placers by sifting sediment through a placer or miner's pan. Wet panning in streams and rivers as well as dry panning through land sediment and washes commonly yield ounce-size nuggets. A gold nugget weighing one ounce is about the size of a quarter, depending on its shape.
Hone in on the precious metal with a metal detector if panning is not your thing. Finding ounce-size nuggets isn't uncommon.
