Similarly one may ask, why is Blood Falls in Antarctica red?
The deep red coloring is due to oxidized iron in brine saltwater, the same process that gives iron a dark red color when it rusts. The research team calculates that the brine water takes approximately 1.5 million years to finally reach the Blood Falls as it makes its way through fissures and channels in the glacier.
Likewise, what is the largest waterfall in Antarctica? This speck of unusual color is visible from far away – and in the extremely dry climate of McMurdo Dry Valleys one can see very far. Blood Falls were first noticed by Australian geologist Griffith Taylor in 1911 (what is earlier than the discovery of the world's tallest waterfall – Angel Falls in Venezuela).
Similarly one may ask, why is the water in blood falls Red?
When the salty, iron-rich water bleeds out of the openings in the glacier and first comes in contact with the air, the bright red color is produced. When the falls aren't flowing, they turn a dried rust color, like a scab covering a wound. It seems these falls can make you shiver from more than just the cold.
How do I get to blood falls?
According to Atlas Obscura, Blood Falls can only be reached by "helicopter from McMurdo Station (U.S.), Scott Base (New Zealand) or a cruise ship in the Ross Sea." To see these gruesome falls, it's best to apply for an internship — or lead a research expedition.
