Recently bulldozed but the site
REMAINS: The mines are all that is left.
Union had a post office from 1887 to 1888. As with most Maricopa county mines, Union was all talk and no action. Located in 1876, and worked into the early 1900's, Union only produced a guestimated $10,000 in gold. Eventually, a ten stamp mill was erected and the town survived on meager takings from the mine, but not for long. In 1995 the dust of the bulldozers finished demolishing what was left of Union.
