What is it about pyramids that excites the imagination? Their shape? Their size? Height? Age? The complexities and difficulties in their building? Or the sheer grandeur of them?
And what is it about them that get the cranks and conspiracy theorists so fired up? What is it about these constructions that convince some folks they’re made by – or for – aliens? Or that there’s some bizarre coverup by governments to keep people from knowing the “truth” about them?
This week I noticed some odd search terms showing up in my stats page: “antarctica” and “pyramids” in the same line. Not something I’d expect to see in my posts. What silliness is this, I asked myself. That’s gotta be worth exploring. And whoa! I stumbled into a major conspiracy theory I must have missed!
Antarctica, the fifth largest continent, is 98% covered in ice that averages a mile thick. It’s the coldest place on the planet, with temperatures as low as -89C (-128F). But it wasn’t always so. The continent broke away from the Gondwanaland super-continent starting about 160 million years ago. After that it drifted until it arrived where it is and started gathering ice.
It’s been covered in ice for about 15 million years, although before that it was a fairly temperate region. During the entire, short duration of human existence (historically speaking)*, it has been an inhospitable, ice-covered place. And for most of that, it has also been bereft of human habitation.
Antarctica wasn’t even discovered until the early 19th century,although many speculated that a southern continent had to exist, simply for symmetry’s sake. But the extreme conditions, the treacherous oceans that surround it, the dangers of ice, cold and wind simply made it impossible for humans to get there without a reasonably well-built ocean craft. But we did, even though many died in the process of discovery.
Today, the continent hosts a population that ranges between 1,000 and 5,000, depending on season; mostly scientists. Today, too, you can shell out a healthy piece of cash and take a cruise ship to the Antarctic and spend a day oggling penguins or walk on an ice shelf. But you couldn’t live there easily or for long without significant effort and equipment. The rather limited food sources and complete lack of any vegetation larger than tiny, hardy plants mean you have to ship or fly in most of your food, medicine, clothing, building supplies, fuel and everything else for survival.
You can’t build pyramids there. No one can. There isn’t a lot of ground to build on – although there are small places called the Dry Valleys – and there’s no evidence that anyone dug a quarry in any of them to get the stone necessary to build a pyramid. Besides, the valleys suffer from unfortunate katabatic winds: high speed cold winds that can reach 320 km/hr. Even if you could withstand the winds, dryness and cold, you’d have to dig through a deep layer of gravel to reach bedrock – tough, ancient granite, not the easier-to-cut -and-shape limestone and sandstone used by many cultures for monuments.
