Blood Falls seeps from the end of the Taylor Glacier into Lake Bonney. The tent at left provides a sense of scale for just how big the phenomenon is. The phenomenon is due to leaks from a reservoir of ancient saltwater buried under the glacier. Ferrous ions dissolved in the water oxidize on contact with the atmosphere, and and precipitate as insoluble reddish ferric salts. Blood Falls contains at least 17 different types of microbes, and almost no oxygen
