Spotted Lake emerges

This might look like the surface of some distant planet, but Spotted Lake is much closer to home. Just north of the US border in the Okanagan Valley of British Columbia, Canada, the lake's strange coloration is due to its high concentrations of mineral deposits. It's a protected cultural site of the Syilx/Okanagan Nation for its healing properties. Spotted Lake is an endorheic lake, which is a basin where water collects but has no river or sea to drain into. The water level rises with rainfall during autumn and winter and then as the days grow longer and hotter the water lowers as it evaporates. During the hot, dry summers in the Okanagan, Spotted Lake earns its name–large 'spots' in varying hues of blue, green, or yellow become more prominent as the water level drops. The area's closed to the public, but you can get a decent view from the highway. Binoculars recommended.

In the footsteps of giants.

Let's follow in the footsteps of giants, this is one of the most popular tourist attractions in Northern Ireland. The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. It was declared a World Heritage Site by UNESCO in 1986 and a national nature reserve in 1987 by the Department of the Environment for Northern Ireland. The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven, or eight sides. The tallest are about 12 meters (39 ft) high, and the solidified lava in the cliffs is 28 meters (92 ft) thick in places.

Go with the rainbow flow

Today's photo brings us to the banks of Caño Cristales, the 'liquid rainbow' that cuts a prismatic path through the heart of Colombia. From June through November, when the clear water is low, the abundant underwater plants that cover the riverbed show off their red, yellow, green, and blue hues. The star of the show—especially in this photo—is Macarenia clavigera, a riverweed that ranges from bright red to deep crimson or purple depending on its intake of sun rays. In August and September, when the florid flora are at their peak, it's a coveted nature excursion: Because the river's ecosystem is so fragile, visits are limited to guided tours.

Reflections of the night sky

We're featuring this video of the whirling Milky Way over the Totensee, a small natural lake in Switzerland, to remind you that August is a fantastic time for stargazing. In the Northern Hemisphere, the nights are still long and remain warm, so if you're lucky you can catch the always thrilling sight of a falling star. Tonight would be a good night to look for one because we're at the tail end of the annual Perseid meteor shower. Like most predictable meteor showers, it occurs when the Earth's orbit intersects with the long elliptical path of one of the millions of comets that orbit the Sun. It is called the Perseid meteor shower because the bulk of the meteors will appear to originate out of the constellation Perseus. So, turn out the lights, head outside, and look up!

A monster view in Scotland

People love a good mystery. Maybe that's why we've been fascinated by mythical creatures like the Loch Ness monster for nearly 1,500 years. We're looking at Urquhart Castle, a ruin founded in the 13th century, with Loch Ness behind it. As the legend goes, on August 22, 565, an Irish priest named Columba confronted 'Nessie' and commanded the 'water beast' away. Since then, people have claimed to spot, or even photograph the Loch Ness monster, as well as Bigfoot, the chupacabra, the yeti, and other creatures around the world. This subculture practices cryptozoology—the study of hidden animals. Are any of these beasts real? Probably not, but why spoil the fun?

Up in the Highlands

There's a good chance that occupants of that car you can see in this photo, winding along a remote highway in the Highlands of Iceland, won't encounter any other visitors to this desolate region. Accessible only during the summertime, the Icelandic Highlands is a volcanic desert. Frequent volcanic activity in the area creates a porous topsoil full of chemical compounds that aren't conducive to plant growth. Besides, much of the rainfall is quickly absorbed so plant life only appears alongside glacial rivers. Despite this seemingly unwelcome environment, adventurous travelers come to the Highlands every summer to see firsthand an ecosystem so unearthly that NASA conducted training missions here for some of its Apollo astronauts.

Volcanic vineyards

What you can see today in our picture is a bird view of La Geria vineyards, in the Canary island of Lanzarote. They have been there since 18th century and are cultivated following a very special technique, because the vines are planted under the volcanic lapilli, a blanket of ash about two and a half meters thick that covers the land since Timanfaya volcano erupted in 1730 transforming the landscape forever.

To reach the fertile soil, farmers first dig a cone-shaped hole and then build a small stone wall to protect the vines from the trade winds. And since the volcanic ash on the surface prevents rainwater evaporation and captures environmental moisture, plants do not even need added watering.

The variety the most cultivated in this place is volcanic Malvasia, a very special and also very delicate white grape allowing both dry and sweet wines. Due to its unique characteristics, La Geria has also been a protected area since 1987, just as the neighbour Timanfaya National Park, where you can see up to 25 volcanoes concentrated in 51 square kilometers.

A giant relic in Java

This photo shows the quiet, mist-shrouded wilderness surrounding the Buddhist temple known as Borobudur. The site is among the most-visited attractions on the island of Java, with devout practitioners making pilgrimages to the holy site and curious tourists coming to see the grandeur of the structure. With 504 Buddha statues and 2,672 sculpted relief panels, Borobudur was likely constructed in the 9th century and abandoned in the 14th as much of the Indonesian population converted from Buddhism and Hinduism to Islam.

Over time it became engulfed by the jungle, and only locals knew of its existence. In the early 1800s, the occupying British administration learned of the temple and sent a Dutch engineer and 200 workers to cut down trees, burn vegetation, and dig away the earth to reveal the monument. Borobudur was eventually restored and given preservation status under UNESCO guidelines.

Life in the nearby town of Muntilan and other Indonesian locales will be even more active than usual on August 17, as that date is Indonesia's Independence Day. The nation of islands at the crossroads of the Indian and Pacific oceans declared independence in 1945 and made the date a national holiday eight years later. The people of Indonesia were freeing themselves from three centuries of Dutch rule.

It's National Acadian Day

In honor of Canada's National Acadian Day, we're on the shores of New Brunswick as the ocean recedes to reveal the Bay of Fundy's massive intertidal zone. The tide is a big deal at the bay—more than five times bigger than in most places. Typical tides around the world have a range of 3 to 6 feet, but these waters drop as far as 50 feet from high to low tide.

National Acadian Day celebrates the legacy of the Acadians, Canada's first permanent French residents. The agrarian Acadians first settled what's now Nova Scotia in 1605 and spread to nearby areas, like this one, over that century, developing an identity distinct from the rest of New France. This unfortunately didn't shield them from Old World conflicts as France's longtime enemy, Britain, occupied and tried to conquer Acadia multiple times, finally succeeding in 1710. The British ultimately expelled the Acadians four decades later, a forced relocation to other British colonies where Acadians were often pressed into servitude—or to France, the mother country many Acadians never knew, and to which many wouldn't survive the voyage.

But that tragic chapter is far from the end of the Acadians' story. Some of them eventually returned to Acadia, and their culture still permeates Canada's Maritime provinces—as well as another unlikely locale. Thanks to France's friendly 18th-century relations with Spain, many exiled Acadians were able to settle the then-Spanish-controlled bayous of Louisiana—where 'Acadian' eventually morphed into 'Cajun.'
