Synopsis

It is the only rock we consume – a treasure vital to our existence. It boasts more than fourteen thousand applications, from clearing ice from roadways to purifying our water supply. We blast it from immense caverns far below the earth’s surface, collect it through solar evaporation in coastal ponds, and extract it using powerful hydraulic drills that reach deep underground veins. The realm of salt…a thought worth having the next time you season your food with those simple white grains.
