Jack Thompson, a longtime member of the Colorado Springs Mineralogical Society is an expert in judging competitive display cases.
I usually attend the "main event" in order to see the various display cases and ogle at the minerals and wonder why my expeditions have never produced such fine specimens? This year was a little different as my newly replaced knee and my upcoming new hip really slowed down the walking. I was essentially confined to the center stage of the Mart and unable to visit the various hallways with fine mineral and fossil dealers. But, I am hopeful that the new body parts will allow much more mobility in the near future!
My favorite display was Minerals and the Instruments used to Study Them exhibited by Dan and Dianne Kile.
The theme for the 48th Show was Minerals of the Southwest so I expected numerous specimens of Arizona azurite and malachite; the exhibits did not disappoint. There were several cases displaying minerals from Utah, especially large nodules of variscite and crandallite. These two aluminum phosphates are greatly sought after by collectors, especially those collected form the Little Green Monster Claim in Clay Canyon near Fairfield in Utah County. This mine was worked by two collectors with connections to the Colorado Springs Mineral Society---Ed Over and Art Montgomery.
The green to yellow phosphate nodules containing variscite [AlPO4-2H2O] and crandallite [CaAl3(PO4)(PO3OH)(OH)6] collected from the Little Monster Claim are probably the “best in the world.”

I have never collected Arizona Fire Agates but certainly observe such in dealer displays.
