Antarctica Blood Falls mystery solved? Find out the source of the red water


The source of Antarctica's gruesome looking Blood Falls has finally been discovered putting an end to the mystery of where the red water came from. At first it was thought some form of algae was discolouring the water, but that hypothesis was never verified. Researchers from the University of Alaska Fairbanks have now concluded that the blood resembling liquid is iron-rich brine that comes from a more than million-year-old lake trapped beneath the Taylor Glacier. The colour of the water can be attributed to oxidised iron in brine. It is the same process that gives iron a dark red colour when it rusts. Researchers used radio echo sounding to detect the saltwater's path. They discovered that the water had taken close to 1.5 million years to finally reach Blood Falls as it made its way through fissures and channels within the glacier.


Water would normally freeze under such extreme cold conditions, but researchers say a combination of the heat given out during the freezing process and the lower freezing temperature of salt water allowed the lake's water to keep its form. The brine scrapes iron from the bedrock as it seeps through the ice to give it the colour red. Source: https://www.yahoo.com/news/antarctica-blood-falls-mystery-solved-094420671.html

Civita di Bagnoregio, Italy


Civita di Bagnoregio is a town in the Province of Viterbo in central Italy, a frazione of the comune ofBagnoregio, 1 kilometre (0.6 miles) east from it. It is about 120 kilometres (75 miles) north of Rome.

Civita was founded by Etruscans more than 2,500 years ago. Civita was the birthplace ofSaint Bonaventure, who died in 1274. The location of his boyhood house has long since fallen off the edge of the cliff. By the 16th century, Civita was beginning to decline, becoming eclipsed by its former suburb Bagnoregio.


At the end of the 17th century, the bishop and the municipal government were forced to move to Bagnoregio because of a major earthquake that accelerated the old town's decline. At that time, the area was part of the Papal States. In the 19th century, Civita's location was turning into an island and the pace of the erosion quickened as the layer of clay below the stone was reached in the area where today's bridge is situated. Bagnoregio continues as a small but prosperous town, while Civita became known in Italian as il paese che muore ("the town that is dying"). Civita has only recently been experiencing a tourist revival.

The Largest Dinosaur Footprint Ever Has Been Found in Australia's 'Jurassic Park'

At low tide near Broome (Western Australia), you can see some of the biggest 
dinosaur tracks in the world, made by sauropods about 130 million years ago.

On a 25-kilometer stretch of coastline in Western Australia lies a prehistoric treasure trove. Thousands of approximately 130 million-year-old dinosaur footprints are embedded in a stretch of land that can be studied only during low tide, when the sea — and the sharks and crocodiles that inhabit the region — can't hide them. What scientists found there is truly special, according to a study recently published in the Journal of Vertebrate Paleontology. "Nowhere else has as many types of dinosaurs represented by tracks than Walmadany does," Steve Salisbury, a paleontologist at the University of Queensland and the lead author of the study, said in a video describing the area. Included among those many dinosaur tracks is the largest dinosaur footprint ever found. At approximately 1.75 meters long (about 5 feet, 9 inches), the track came from some sort of giant sauropod, a long-necked herbivore.
