American Minerals!
While I typically focus on minerals from other countries, COVID has somewhat forced me to look a bit more locally. This update contains a group of specimens from the USA, with an emphasis on the midwest. When this region is mentioned most people default to thinking about the old southern Illinois fluorite mines, or the (rather boring for the relative homogeneity of its specimens, in my opinion) Elmwood Mine. But this region is also dotted with hundreds of quarries that supply everything from crushed stone for roads and sand for glass, to the raw materials from cement and even animal feed. At many of these, minerals such as calcite, celestite, and barite are encountered. While it would be impossible to list specimens from all of these locations, I have tried to post at least one specimen from as many of the main (and a few rather obscure) localities as possible. In some ways, if nothing else, this update can actually even be a quick reference to the main localities in the area.
