Geologists say the latest Kilauea eruption in the Southwest Rift Zone left behind vibrant sulfur deposits. While it looks like spray paint, the yellow lines are actually crystals made of sulfur.

Study: Sulfur helps gold reach Earth’s surface. Scientists have long suspected that sulfur, which forms strong chemical bonds with gold, allows it to be transported up to the surface.

The company eventually expanded its reach as it discovered other sulfur deposits in areas south of Sulphur. Other companies jumped on the technology when Frasch's patent expired in the 1920s.
