Rare Earth Minerals

Mineral Maps and Books!


In addition to selling minerals, we also carry a variety of products relating to the mineralogy, history, and geology of the Black hills, in addition to other non mineral products. We have maps of mining ghost towns, historical mineral information, and periodic tables of elements, using minerals as examples.  Take a look at our Maps and Books section.
