Blood Falls in Antarctica
Blood Falls seeps from the end of the Taylor Glacier into Lake Bonney in the Antarctic. Scientists believe a buried saltwater reservoir is partly responsible for the discoloration, which is a form of reduced iron.

Blood Falls is an outflow of an iron oxide-tainted plume of saltwater, occurring at the tongue of the Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica.
Iron-rich hypersaline water sporadically emerges from small fissures in the ice cascades. The saltwater source is a subglacial pool of unknown size overlain by about 400 meters of ice at several kilometers from its tiny outlet at Blood Falls.
