Antarctica’s unsettling blood waterfall

Blood Falls, Antarctica.
Iron oxides cause the blood-like coloring of this waterfall in Antarctica.

Nature’s marvels are boundless, and one of its most visually disturbing is a certain blood-red cascade found in Victoria Land, East Antarctica (aptly named “Blood Falls“). Fortunately for the squeamish, it’s not actually blood:

Blood Falls is an outflow of an iron oxide-tainted plume of saltwater, flowing from the tongue of 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 metres (1,300 ft) of ice several kilometers from its tiny outlet at Blood Falls.

The reddish deposit was found in 1911 by the Australian geologist Griffith Taylor, who first explored the valley that bears his name. The Antarctica pioneers first attributed the red color to red algae, but later it was proven to be due to iron oxides.

Surely a sight to see! Given the remote location of Blood Falls, though, it’s unlikely to appeal as a tourist destination to any but the hardiest and most well-heeled of travelers.


Horrifying 8-foot-vortex opens up in Texas lake

Said to be large enough to “swallow a boat,” the Lake Texoma vortex seen below is actually the result of intentional draining due to high water levels following Texas’s record rainfall this summer. You wouldn’t need to tell me twice to keep my distance from this monster:

You can read more here. Of course, even this impressive whirlpool has got nothin’ on the famous disappearing Lake Peigneur, a catastrophic vortex which devoured  a “drilling platform, eleven barges, many trees and 65 acres (260,000 m2) of the surrounding terrain.”


It’s raining spiders in Australia

Australia, the Land Down Under, the place where everything is poisonous, just got even more terrifying. You read the headline right: it is raining spiders in Australia:

Millions of tiny spiders recently fell from the sky in Australia, alarming residents whose properties were suddenly covered with not only the creepy critters, but also mounds of their silky threads. But that’s not where the frightful news ends: Experts say that such arachnid rains aren’t as uncommon as you might think.

Of course the question, then, is why is it raining spiders in Australia? (Tautological answers will not be accepted.) The answer is just as unsettling as the phenomenon itself. According to Rick Vetter, a retired arachnologist at the University of California, Riverside, witnesses

likely saw a form of spider transportation known as ballooning. “Ballooning is a not-uncommon behavior of many spiders. They climb some high area and stick their butts up in the air and release silk. Then they just take off,” Vetter told Live Science. “This is going on all around us all the time. We just don’t notice it.”

Next time I travel to Australia, remind me to bring an umbrella.
