When we were there last year, we spent just a couple hours at some mine dumps west of Cedar City and found some great specimens&#8230;several of these turned out to be fluorescent under a standard black light (long wave UV). Since I really want to track down some more of these awesome rocks, I ordered a couple&nbsp;<a href=\"http:\/\/www.polmanminerals.com\/html\/uvp__llc.html\" target=\"_blank\" rel=\"noreferrer noopener\">portable UV lamps<\/a>&nbsp;to bring with us. The first one arrived a few days ago&#8211;a 4 watt short wave UV lamp. I hadn&#8217;t seen any of our collection under short wave UV yet, so I got busy shining it on everything we had. I was excited to see that this lamp nearly doubled the number of fluorescents we have&#8211;and some of them are stunning!<\/p>\n\n\n\n<p>A four watt lamp is very low power, but it&#8217;s enough to examine things (and was all I could afford for the time being). I won&#8217;t be able to stalk around after dark and shine it on a massive hill of mine tailings and see anything, but it works well enough that I should be able to throw a black tarp over myself and get in close to see if anything lights up.<\/p>\n\n\n\n<p>Here are the photos of our current fluorescent collection. It contains rocks from the Comstock Mine Dump, Iron County, UT; Chalcedony from Brian Head, UT; Rocks from north of La Madera, NM; Petrified Wood from Hurricane Mesa, UT; and some small, bright red specimens from south of Cleator, AZ.
