Last month I wrote about the Arkansas portion of Wayne County Gem and Mineral Club’s November field trip south (quartz, quartz and more quartz). But we did not stop there. After three days of collecting SiO2 in and around Mt. Ida, Arkansas, ten of us pointed our large black van east and headed to Tennessee and North Carolina.

I bought it and came home to research the geology and age of my new find. Immediately, things got complicated.
