Washington state has some great gold

Washington has not been a major gold producer, but they have produced over
2,000,000 ounces of the yellow stuff. Considerable unexploited virgin
placer deposits are known and mining claims can still be worked at a profit
in Washington. For a complete description of every lode and placer mine,
claim, or prospect in Washington request Bulletin 37, Inventory of Washington,
by Marshall T. Hunting. It can be purchased from State Department of Natural
Resources, Geology and Earth Resource Division in Olympia, Washington.
