sulfur pools
Geothermal yellow waters
Sulfur pools are bodies of water, typically hot springs or geothermal features, containing dissolved sulfur compounds.
They're characterized by their distinctive rotten-egg smell from hydrogen sulfide gas and often display vivid yellow, green, or blue coloration.
Found in volcanic regions like Yellowstone, they're too acidic and hot for swimming but draw tourists for their otherworldly appearance: Steam rose from the sulfur pools at dawn.
