Located in Antarctica, Blood Falls is a five story waterfall that pours out of the Taylor Glacier in the continent's McMurdo Dry Valleys and is something out of this world. Its bright red color is alarming yet stunning. The deep red falls were first discovered in 1911 and it wasn't until last year, that scientists discovered why the waters were red. According to research by the University of Alaska Fairbanks, the dark red coloring is due to oxidized iron in brine saltwater, the same process that gives iron a dark red color when it rusts. This is truly one of the most eerie waterfalls on our Earth; with water so salty it is more like brine.
