1 . In the 1960s, while studying the volcanic history of Yellowstone National Park, Bob Christiansen became puzzled about something that, oddly, had not troubled anyone before: he couldn’t find the park’s volcano. It had been known for a long time that Yellowstone was volcanic in nature — that’s what accounted for all its hot springs and other steamy features. But Christiansen couldn’t find the Yellowstone volcano anywhere.
Most of us, when we talk about volcanoes, think of the classic cone(圆锥体) shapes of a Fuji or Kilimanjaro, which are created when erupting magma(岩浆) piles up. These can form remarkably quickly. In 1943, a Mexican farmer was surprised to see smoke rising from a small part of his land. In one week he was the confused owner of a cone five hundred feet high. Within two years it had topped out at almost fourteen hundred feet and was more than half a mile across. Altogether there are some ten thousand of these volcanoes on Earth, all but a few hundred of them extinct. There is, however, a second less known type of volcano that doesn’t involve mountain building. These are volcanoes so explosive that they burst open in a single big crack, leaving behind a vast hole, the caldera. Yellowstone obviously was of this second type, but Christiansen couldn’t find the caldera anywhere.
Just at this time NASA decided to test some new high-altitude cameras by taking photographs of Yellowstone. A thoughtful official passed on some of the copies to the park authorities on the assumption that they might make a nice blow-up for one of the visitors’ centers. As soon as Christiansen saw the photos, he realized why he had failed to spot the caldera: almost the whole park—2.2 million acres—was caldera. The explosion had left a hole more than forty miles across—much too huge to be seen from anywhere at ground level. At some time in the past Yellowstone must have blown up with a violence far beyond the scale of anything known to humans.

2 . For thousands of years, Chinese writers have travelled all over the country to take down notes about the geographical conditions of each city. Among them, well-known Chinese geographer and writer Li Daoyuan, in the Northern Wei Dynasty (386-534), composed his book, Commentary on the Water Classics, after studying the original literary version, Water Classics. He later expanded the river records to 1, 252 from the original 137.
The book is now being studied again by Professor Li Xiaojie and his team from Fudan University. They have been using drawing software and 3D modelling to recreate the waterway situations on a map based on the book description. So far, they have completed research on four rivers.
“Ancient people knew really well how to apply the power of nature to technical considerations,”Li said, giving the example of Qianjin’e, one of the most famous ancient water conservation projects in Luoyang, Henan. In order to lead the river into the city for irrigation (灌溉) in ancient Luoyang, the officials built a canal branch by separating a northwest-southeast river. However, the canal water wasn't enough to support the citizens in dry seasons. To solve that, on the northern side of the canal branch, the officials built a reservoir (水库) and a channel to lead the water to the canal branch, where the waterways would converge and flow together to the city.
In Commentary on the Water Classics, a total of 2, 800 cities are recorded with details. Still, the process of recreation takes much effort. After doing a lot of text analysis and fieldwork, the team has gradually created the model with 3D modelling software based on repeated deductions (推论).
For Professor Li, the book is not only a record of the natural landscape over 1, 000 years ago, but also a detailed description of humanity and culture and a treasure for today’s reference.

7 . The village of Misfat al-Abriyeen has changed its fortunes by transforming mud-brick homes into fine hotels. The village of 800 people, located on the cliffs of Oman’s “Grand Canyon“, opened its narrow streets six years ago to foreigners and locals seeking adventure in the deserts and green corners of the Gulf area.
Villager Yacoub al-Abri said it all started in 2010 when his uncle suggested they take another look at the mud houses that had lain ignored for years in the ancient settlement about three hours’ drive from the capital Muscat. The owners had abandoned the centuries-old homes, fearing they could topple, and moved to the opposite side of the village where they built new accommodation.
The brown-walled homes, made of mud bricks with palm-leave roofs, were tuned into simple but elegant inns with wood furniture and handcrafts made using sill banded down from their ancestors.“We started with only five rooms, then we increased the number and bought other old houses. Today we have 15 rooms and there are plans to continue expanding until we reach 50,” Abri said.
At an altitude of more than 1,000 meters, the tiny village which is home to the Abri tribe is a charming collection of traditional houses located along dozens of small alleys (小巷) overlooking lands bursting with banana plants and citrus and palm trees. It is part of a region known as the Grand Canyon of Oman where tourists can hike the rocky mountains and valleys, and explore the old ways of local people. The region is also famed for its centuries-old stories that are still widely told in similar villages across the country.
Renoda, a Dutch psychologist living in Muscat, was visiting with three of her friends. “It’s perhaps the 10th time that I have visited this hotel since last year. I come here for a night or two every month, seeking calm, relaxation and comfort,” she told AFP.

10 . Lost cities that have been found
The White City
In 2015, a team of explorers to Honduras in search of “the Lost City of the Monke God” led to the discovery of the White City. It is believed that local people hid here when the Spanish conquerors (征服者) occupied their homeland in the16th century.
Canopus and Heracleion
The Egyptian cities Canopus and Heracleion, where Queen Cleopatra often visited, weren’t found until 1992. Artifacts (史前器物) showed that the cities once highly developed as a trade network, which helped researchers piece together more about the last queen of Egypt.
Machu Picchu
A Yale professor discovered “the Lost City in the Clouds” in 1911. Machu Picchu displays the Inca Empire at the height of its rule. Abandoned in the 16th century for unknown reasons, the city was hidden by the local people from the Spanish conquerors for centuries keeping it so well preserved.
Troy
The ancient city of Troy in Homer’s The Iliad was considered a fictional setting for his characters to run wild. But in 1871, explorations in northwestern Turkey exposed nine ancient cities layered (层叠) on top of each other, the earliest dating back to about 5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.
