A strange and beautiful world

Some of the strangest, most beautiful sights in the universe occur right here on planet Earth. Before humans developed the miraculous tool of scientific methodology, our earlier selves devised all sorts of myths and legends for how these phenomena came into being, many originating with the spirit world – although alien invasions have factored into a lot of recent wishful-thinking attempts at explanation. As we document below, some of these wonders of the natural world have already been explained – sometimes simply, sometimes after many decades of research and thought – by scientists; the origins of others, though, continue to elude us.

It was once believed by a certain subset of theorists that the thousands of geoglyphs scratched into a high desert plateau in Peru were the work of extraterrestrials trying to mark a landing site for their spaceships. But this Unesco World Heritage site is undeniably the work of ancient humans; the representation of a condor, a massive bird of prey, seen here, along with massive depictions of killer whales, flowers, hummingbirds and monkeys, was the mind-boggling handiwork of the prehistoric Nazca people, who etched these lines between 200 BCE and 500 CE. Why and how? Those are questions that remain to be answered. Some scientists believe they’re somehow connected to the Nazca’s searches for drinking water, or that they represent constellations seen in the night sky. But how they were accomplished without sophisticated engineering tools is anyone’s guess.

Fairy Circles

The Namib Desert in Namibia is home to mysterious circles of vegetation, creating a landscape that mathematician Corina Tarnita described to Science Friday as looking “like a polka dot dress”. Measuring between 3 and 20 metres in diameter, these circles of barren vegetation are not actually the work of fairies, or, according to local legend, of the gods leaving behind their footsteps. Still, the real cause remains elusive, with scientists hypothesising that they are created by thirsty plants stretching out for water in an arid locale; or that underground networks of termites have munched the vegetation into shape.

Sailing Stones

Racetrack Playa, in Eastern California’s Death Valley, is home to the mysterious sailing stones, which appear to move on their own overnight, even leaving trails in the mud. In the 100 years since this phenomenon was first noticed, scientists have theorised that magnetism was the cause for the movement (although other, less learned theories implicated aliens). However, in 2014, the sailing stones were studied up close and personal, and it was discovered that the dry lake bed on which they sit becomes covered in water when night comes, which quickly freezes. By morning, the ice has melted and this action, along with the region’s winds, propel the rocks a few centimetres to metres away from their day-before spots.

Palouse Falls

The odd-ball landscape of Washington State’s so-called ‘scablands’ baffled geologists for decades; their basaltic features, including Palouse Falls pictured here, spread across some 26,000 kilometres of the Columbia Plateau, seemed to have been sculpted by a huge, rapidly-moving deluge of water – but there was no evidence to support this concept. Scientists couldn’t imagine where such floodwaters could have come from, nor where they wound up after they’d sculpted this terrain. But later research led to the conclusion that the region had been created by not one, but as many as 80 floods over one or two thousand years.

Trona Pinnacles

They’re so other-worldly-looking that the Trona Pinnacles, on the site of a US Navy base in California, have been used as a backdrop in numerous movies set in outer space. But despite their alien appearance, there’s nothing really mysterious about these mini-mountains, some of which reach a height of 40 metres. They’re called tufa towers, and they’re made of calcium carbonate that formed underwater when freshwater met and interacted with the alkaline water of Mono Lake. This lake itself is about a million years old, and thanks to minerals that continue to wash into it from surrounding lakes, it’s 2-1/2 times saltier than the ocean.

Chocolate Hills

This ‘geological oddity’, as National Geographic calls this range of even mounds dotted across the Bohol Province in the Philippines, has lush vegetation that turns brown during summer die-off, which accounts for the name. But less evident is how they came to be, and how they managed to develop so symmetrically. Myths abound, of course, featuring weeping and warring giants. So do scientific theories, including one that suggests that the 1,200+ mounds, averaging about 50 metres in height, were caused by eroding limestone stacked on clay. But the core mysteries of their shape, size and appearance to date remains unsolved.

Giant’s Causeway

A giant is also in the legend of how this outcropping of volcanic rocks came to be formed on the coast of Northern Ireland, which magically appears as a path to help a mere mortal intent on protecting his homeland. In reality, though, this massive zigzag of 40,000 basalt columns at this Unesco World Heritage site is the result of an undersea volcanic eruption some 60 million years ago, which pushed lava up through the cold coastal waters, cooled it and, with the erosion of thousands of years, eventually shaped them into these irregular ‘steps’.

Lake Hillier

In the remote south of Western Australia is Middle Island, the largest of 105 islands that make up the Recherche Archipelago, locally known as the Bay of Isles. On the edge of Middle Island is the pink Lake Hillier. Why the colour of the water is pink remains a true mystery of science. The small, salty lake flouts the convention of other weirdly coloured lakes around the world; namely, it looks pink no matter how close you get to it – even when it’s bottled; and it stays pink all the time. Why? No one knows for sure. Top theories are that the pink colour has to do with the presence of Dunaliella salina microalgae, an algae that produces carotenoids, a pigment found in carrots. The presence of halophilic bacteria in the salt crusts could be another explanation, while another theory believes it is the result of a reaction between the lake’s salt and its sodium bicarbonate deposits.

Dallol Hot Springs

These hydrothermal hot springs at Ethiopia’s Afar Triangle – which may be the hottest place on Earth – produce some of the most eye-boggling colour combinations occurring in nature. Filled with extremophiles – organisms that manage to live in extremely hot, cold, salty or sugary environments, seemingly against all odds – the hot springs’ colours, despite their other-worldly appearance, are actually quite easily explained by science: groundwater that’s heated by magma dissolves salts and pushes them to the surface, where they dry into these fantastical apparitions.
