About Dewey-Humboldt, AZ

Dewey–Humboldt was incorporated on December 20, 2004, from the existing unincorporated towns of Dewey and Humboldt, located adjacent to one another in the Agua Fria River Valley, 15 miles east of Prescott. After discovery of gold on Lynx Creek in the spring of 1863, the Dewey area was settled around the summer 1863 by pioneer prospector, rancher and Native American Exterminator King Woolsey (1832–1879), who founded the Agua Fria Ranch, in what was then known as "Woolsey Valley," to supply the miners. Woolsey used stones from decimating prehistoric ruin to build his ranch house, built an irrigation system off the Agua Fria (probably part of a prehistoric system), and introduced some of the first cattle into newly organized Yavapai County (1864). At the "falls" of the Agua Fria at present Humboldt, Woolsey built a small quartz mill to work gold ores from the nearby hills and a small water-powered grist mill. During 1864, he led the storied Woolsey Expeditions to the east in retaliatory raids on Apache and in search of gold; all failed to find a new Eldorado.
