Walker District, Yavapai County, Arizona As in the other Western States the first discoveries of gold in Arizona were placer deposits. The most productive placer mining era was 1858-80. Lode deposits were discovered later, circa 1900, and they furnished the bulk of the early gold output of the State. By 1965 Arizona ranked eighth among the gold-producing States. Yavapai County, located in the Central Mountain Region, was the source of most of Arizona’s placer gold. Generally found in wet and dry streamcourses, Arizona’s general lack of water means that dry recovery methods such as dry-washing must be used. Most of the Arizona gold discovered before the 1990s was melted making the specimens which are in existence rather scarce. Now a rarely seen locality for gold, this Arizona placer nugget has a interesting river-tumbled flattened form and “mitten-shaped” outline with tiny traces of arsenopyrite in the crevices and a rich buttery patina. Measuring 1 ¾ x 1 ¼ x ¼in
