Many mines are found in the vicinity of the small town of Wickenburg, northwest of Phoenix.

A few years ago my friend Joe McAnney and some others went in search of the fabled UFO Claim.  They're not sure if they found the right spot or not but they did find some interesting things.  I got from Joe a single flat of fluorescents rich in Powellite and other minerals.  These are the last 3 pieces from this locale that I expect to have other than a couple in my personal collection.
