Patti Cummings, a member of the Bloomington Indiana Grotto caving group, "They painted it on crystals, too, on quartz crystals," Cummings said.
I'm surprised a grotto member would describe cave formations as quartz
crystals, which are generally quite rare in caves. Is there really quartz in
Buckner's? I'll bet it was dogtooth spar. Otherwise, that was a good report
of catching vandals red-handed.
