We may finally have an explanation for a red waterfall in Antarctica that has puzzled visitors and researchers since its discovery in 1911. Blood Falls may owe its rusty, bloody color to salty water that has been trapped under the Taylor glacier for more than 1 million years.
According to a new study published in the journal Glaciology, the color of the falls can be traced to iron-rich salty water, since the iron turns the brine red when it meets the air.
Researchers at the University of Colorado and the University of Alaska used radio-echo sounding to transmit and receive electrical pulses on the glacier. This allowed them to view what was happening under the ice. Read more...
