Welcome to the Ring of Fire

Today we're visiting the pair of volcanoes known as Tolbachik—the flat-topped Plosky (Flat) Tolbachik on the left of our image, and the majestic Ostry (Sharp) Tolbachik on the right, which soars 12,080 feet above the Kamchatka Peninsula in far eastern Russia. These are just two of approximately 160 volcanoes that dot the region; 29 of them, including the Tolbachik complex, are still active. In fact, there is so much volcanic activity here that UNESCO calls the peninsula 'one of the most outstanding volcanic regions in the world,' and has designated it a World Heritage Site.

The Kamchatka Peninsula juts out from the Russian mainland between the Sea of Okhotsk to the east and the Pacific Ocean and Bering Sea to the west. The sparsely populated peninsula makes up the western edge of the Ring of Fire, a chain of volcanoes along the Pacific Ocean that account for 90% of the world's seismic activity. Wild, remote, and primal, Kamchatka is home to an abundance of wildlife: arctic fox, tundra wolves, reindeer, lynx, huge Chukotka moose, and the Kamchatka brown bear that can tip the scales at 1,400 pounds.

There once was a lighthouse from...

Nantucket is the island home of about 12,000 people. But venture to its sandy northern reaches, composed of narrow sand spits and only accessible via 4x4 vehicles, and you might not bump into many folks on your way to this historic—and still very important—lighthouse.

The Great Point Light on the island's northernmost tip traces its origin to 1784, a time when Nantucket was world famous—not so much for appearing in countless (often bawdy) limericks, but as the epicenter of the American whaling industry. Herman Melville wrote that Nantucket whalers once controlled two-thirds of the globe's waters, and to get home, all those whaling ships had to navigate the perilous shoals between the island's north shore and nearby Cape Cod. This lighthouse was the solution, first in the form of a wooden tower that burned in 1816, then a stone version toppled by a storm in 1984. The current structure, built partly with materials from the previous one, was dedicated in 1986 and has been in official operation since.

Take in a show on your Roman holiday

In the hills around Pamukkale, Turkey, you'll find the ancient ruins of Hierapolis, which thrived here as holy and healing destination through Greek, Roman, and Ottoman times. The city was founded as a thermal spa in 190 BCE by Eumenes II, the king of Pergamon and was likely named after the wife of the legendary founder of the Pergamene dynasty, Hiero.

The amphitheater so prominent in this aerial view was built in the second century CE under Roman Emperor Hadrian. Renovated several times over the next 160 years—once to accommodate aquatic shows--the theater would have seated about 15,000 people. An earthquake in 1354 finally toppled the ancient city and it was abandoned until it was excavated by German archeologist Carl Humann in the 19th century. Today, the complex retains some of the best-preserved decorative features of any ancient Roman theater, with friezes of Roman Emperor Septimus Severus and his family, as well as the Greek gods Dionysus, Artemis, and Apollo.

Canada's $20 view

For Canada Day, we're looking at Moraine Lake in Banff National Park. And if you're thinking that this amazing view is worth more than $20, you're right. But this priceless scene was once featured on Canada's $20 bill, hence the nickname. Canada Day, celebrated on July 1, commemorates the date in 1867 when Canada was recognized as a self-governing country under the British Empire It's not exactly Canadian Independence Day–it marks the passing of the Constitution Act of 1867, which was the first major step toward Canada's sovereignty.

Moraine Lake is just one of the many beautiful areas in Canada's oldest national park. Located in Alberta's Rocky Mountains, Banff covers more than 2,500 square miles–though we should say 6,641 square kilometres. After all, it's Canada Day.

Boating on the Bojo

The Bojo River has been the lifeline for the people of Aloguinsan, a sparsely populated municipality of Cebu Province in the Philippines. This region of Cebu only recently became a tourist destination when locals started offering cruises along the Bojo in small, outrigger-style boats like the one seen in this photo. Even with this new industry boosting the local economy over the past few years, Aloguinsan remained an out-of-the-way spot for tourists—larger towns and cities nearby still attracted more visitors. But the remoteness of the Bojo was always part of the selling point: Visitors who made the effort to come take a ride down the river would get taste of the quiet life in the fishing villages along the banks.

The mystery of As Catredrais

The beach of As Catedrais (The Cathedrals) we show you in our picture is one of the most beautiful and mysterious in northern Spain. It’s on the Way of Saint James (Camino de Santiago), very close from Galician town of Ribadeo, and its real name is Aguas Santas beach (Holy Waters). Everybody calls it The Cathedrals because of the arches growing from the sand tongue, which look like the buttresses of a Catholic church. They’re supposed to be natural carved by the action of salty water and wind over millions of years. And the most superstitious locals belive there’s a door in this place connecting with the beyond.

However, all these theories and legends could collapse like a house of cards If it was not the sea, but the man, who carved the rock long time ago. Or at least, if both, men and nature, worked together to form this landscape. A group of expert geologists maintain from some years now these arches and caves are not natural but the remains of an ancient Roman gold mine. They refer to archaeological studies confirming the presence of this civilization in the area looking for gold, and believe certain capricious forms of the stone suggest the action of men rather than nature or spirits.

Looking for peace on the precipice

The Sanctuary of Madonna della Corona sits on an outcropping almost 2,500 feet high overlooking the Adige River Valley in Northern Italy, near the city of Verona. Since the Middle Ages, this spot has been a destination for religious pilgrimages. The faithful are drawn no doubt by the views and, perhaps, the dangerous path to get there--enlightenment shouldn't come easy.

Over the centuries, the structure has evolved from a hermitage to a church, first inaugurated in 1530, and eventually to a sanctuary for contemplation and reflection. In the mid-1970s, architect Guido Tisato oversaw a major renovation, including digging out more of the mountain to add additional space. Today, visitors can reach the sanctuary from above via a paved path or from below, on a longer trail, known as the 'Path of Hope,' that ends with a steep staircase zigzagging upward. We think those who manage the climb up may be justified in feeling a little superior.

Hoisting a flag for seafarers

Here above the chilly seas off Iceland, we're peering down at a tall ship called the Gorch Fock—a training vessel of the German Navy. Built in 1958, it replaced the original 1933 Gorch Fock, which was seized by the Soviets in the wake of World War II (but is now back home in Stralsund, Germany, as a museum ship). Because traditionally rigged tall ships are valued as tools for learning general sailing skills, the '58 Gorch Fock is still in official service—but for much of the 21st century, it's been in and out of drydock for repairs and safety improvements.

Today marks the International Day of the Seafarer, which serves to highlight how crucial overseas shipping is to daily life around the world. The event is also intended to remind us of the bravery and sacrifice shown by sailors of all stripes as they endeavor to perform this essential function. As much as 90% of all cargo travels by sea at some point in its journey to the store or your door, so next time you encounter an old sea dog on a dark and stormy night, be sure to say thanks.

Beautiful baobabs

Today we celebrate the island nation of Madagascar, located off the southeast coast of Africa, which became independent of France 60 years ago today, in 1960. Madagascar's national tree is the stately baobab—impossibly tall and imposing, but a little silly at the same time. In fact, its nickname is the 'upside-down tree,' since it looks like it was planted with its roots in the air. Six of the world's nine baobab species are native to Madagascar. The trees we're looking at today are the Grandidier baobab, the largest of them all, lining the Avenue of the Baobabs near the western coast.

This species can grow up to 100 feet tall and 36 feet in diameter, a measurement that can actually change as the trunks store water during rainy seasons to help them survive in times of drought. Baobabs are also known for their longevity; those growing along the Avenue of the Baobabs are estimated to be 2,800 years old. Locally, Grandidier baobabs are referred to as 'renala,' or 'mother of the forest.'
