Missing Penguins Found

Previously Unknown “Supercolony” of Adelie Penguins Discovered in Antarctica
For the past 40 years, the total number of Adélie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining—or so biologists have thought. A new study led by researchers from the Woods Hole Oceanographic Institution (WHOI), however, is providing new insights on this species of penguin.

In a paper released on March 2nd in the journal Scientific Reports, the scientists announced the discovery of a previously unknown “supercolony” of more than 1,500,000 Adélie Penguins in the Danger Islands, a chain of remote, rocky islands off of the Antarctic Peninsula’s northern tip.

“Until recently, the Danger Islands weren’t known to be an important penguin habitat,” says co-PI Heather Lynch, Associate Professor of Ecology & Evolution at Stony Brook University. These supercolonies have gone undetected for decades, she notes, partly because of the remoteness of the islands themselves, and partly the treacherous waters that surround them. Even in the austral summer, the nearby ocean is filled with thick sea ice, making it extremely difficult to access.
Maybe they just don't like visitors. I just hope they don't have to move someplace worse because the scientists found them
Yet in 2014, Lynch and colleague Mathew Schwaller from NASA discovered telltale guano stains in existing NASA satellite imagery of the islands, hinting at a mysteriously large number of penguins. To find out for sure, Lynch teamed with Stephanie Jenouvrier, a seabird ecologist at WHOI, Mike Polito at LSU and Tom Hart at Oxford University to arrange an expedition to the islands with the goal of counting the birds firsthand.

When the group arrived in December 2015, they found hundreds of thousands of birds nesting in the rocky soil, and immediately started to tally up their numbers by hand. The team also used a modified commercial quadcopter drone to take images of the entire island from above.

The Pyramids of Antarctica

THIS is the Google Earth location which conspiracy theorists are now claiming is a mysterious Antarctic pyramid.

The bizarre spot has been shared widely on YouTube, with enthusiasts claiming that it is proof humanity once lived in the area and built a man-made structure.
Kind of looks like a crooked sided pyramid, doesn't it.
Some scientists have theorised that the frozen area of Antarctica was once much warmer – with possible temperatures of up to 20C.

Addressing the topic of climate in the region, Dr Vanessa Bowman of the British Antarctic Survey once said: “Go back 100 million years ago and Antarctica was covered in lush rainforests similar to those that exist in New Zealand today.”
True enough, if you go back to the era of the dinosaurs. Do we imagine sentient dinosaurs building pyramids in a jungle Antarctica? If so, it would be unlikely for the pyramid to survive. Look at what a mere 4000 or so years have done to the Egyptian pyramids.

Actually, there's a pretty simple explanation for a mountain looking like that, volcanic dikes. Looking at the site from the top:

See those two ridges radiating away from the pyramid? Now compare that to Ship Rock in the New Mexico:

The radiating lines are intrusions of erosion magma into splits in the ground around the original volcano, most of which eroded away.

Am I right? Maybe, but it sure seems more likely than a dinosaur civilization or time travelling Egyptians.
