Sulfur is a fascinating element. It is Earth's fifth most common element to be found in the natural world. It typically manifests as a mineral—a sulfide or sulfate. You may have smelled its presence in the “rotten egg” odor of certain natural mineral waters which bubble up from springs. Such springs have long been spa destinations for health and enjoyment, but they can offer incredible, barren beauty as well.
