(Photo: Tribun Travel) Lake Kawah Ijen, or Kawah Ijen crater, doesn’t “sputter” loudly underground compressed carbon gas, it’s just calm there with a beautiful turquoise color. When the night comes, this place completely changes the scenery, no longer as beautiful as the fairy scene, but with a ghostly charm that captivates visitors. The unique feature of the volcanic lake Ijen is that at around 2am to 4am every day, around the crater you can see the phenomenon of blue fire (blue fire) which is likened to “wispy ghost” flames. “. (Photo: Vntravellive) (Photo: Vntravellive) Explaining this unique phenomenon, scientists believe that sulfur is the key factor that makes Kawah Ijen crater so beautiful. The magma chambers beneath the volcano push sulfuric into the lake bed, which combines with dissolved metals in high concentrations, resulting in gas in the lake that turns the water blue. Besides, the above process also makes Kawah Ijen crater the most acidic lake in the world with a pH of 0.5. (Photo: Vntravellive) The best time to visit Indonesia’s unique volcano is between April and October, because this is the dry season, so the weather is relatively favorable for climbing journeys. If visitors come here from November to March, they will encounter more obstacles because the road up the mountain is quite muddy and slippery. Blue flames are only seen when it is dark at night. If you want to witness and admire this scene with your own eyes, you have to climb from midnight to reach the top before dawn (ticket counter opens at 1:00 am). Arriving there, visitors will witness a unique landscape, unique in the world, which is the image of blue flames erupting from the ground. The temperature here is low, especially at night, the temperature can drop to 2 degrees. (Photo: Viator) When the first rays of sunlight appear, the surface of Lake Ijen gradually shows its poetic beauty through the white smoke, which is a pale blue water color, mixed with the brilliant pink color of the dawn. a truly majestic picture of nature, in harmony with both colors and landscapes. (Photo: Nusa Daily) (Photo: Fodor Travel Guide) The higher the sun rises, the more clearly the rocky slopes of the volcanic cliffs reveal their strong, arid lines, enveloping Lake Ijen, which was then brilliant with a haughty jade green color, not and a dreamlike appearance in the mist like early morning. In addition to the magical blue fire, this Ijen volcanic complex also holds another “dark secret” because this is one of the largest and most dangerous sulfur mining places in the world. (Photo: Wonderfulborobudurtours) Daily workers will go into the crater to mine and have to carry 70-90 kg of sulfur on their backs to climb the mountain home. Although the work is hard and adversely affects health, these miners are not equipped with any protective gear, even they have to take dangerous shortcuts to ensure their safety. most trips per day. Thanks to the increasing number of tourists visiting the Kawah Ijen volcano, the miners have found a way to supplement their income by selling sulfur drawings and ornaments for as little as $1.74 per month. each item.

Fruit garden planted on basalt Through the fairy land Buon Choah is also known as Cat village (Choah village, Krong No district, Dak Nong province), formerly mainly Ede people, they took the alluvial sand from Krong No river to name the village. The remote commune of Krong No district is the location of the global volcanic geological park. On the way from Buon Ma Thuot city to Choah village (where there is a volcanic cave complex), we heard Mr. Le Hoang Co, General Director of Dam San Tourism and Trade Company, a passionate explorer, many times. led the delegations to experience and learn about the land and volcanic caves of Dak Nong, sharing: for many years, the people here have lived by the rice trees, drank the river water, lived a kind and loving life. They love the road which is the burning rocks not because of the scorching sun but due to the impact of the volcano, which is quite interesting and strange. Especially the orchards planted on the wrong rocks are full of fruit. Whether it is a rice field or an orchard, when harvested, the yield is unbelievably high. This place has tourism potential, attractive agricultural resources, must combine all the strengths of the region to make products to attract tourists and improve the quality of life of the people. What makes this land poetic beauty is the endless stretch of rice fields, becoming a feature of the material and spiritual life of the people here. The fragrance of rice rose gently through the nose and the golden sun fell to the foot of the hill, Nguyen Thi Yen (Thanh Son village, Choah village) expressed, people call the rice fields in Choah village the golden rice bowl. because ST24 rice variety has good rice quality and high yield. In 1996, her family came here to set up a business, at this time, they grew RVT rice. In 2016, the government experimented with planting ST24, now it has grown the whole field. Her family has 2 hectares of this rice variety, two crops a year for 14 tons/ha and 2 sao of fruit trees: jackfruit, coconut, litchi and 10 cows, with a total income of 300 million VND per year. The newly discovered cave has a length of nearly 1 km The Krong No River appears before your eyes. The large ferry approached the shore, a group of 45 people from a company in crimson uniforms carried luggage onto the ferry. More than a few minutes of moving, touching the shore, each group in turn was arranged to wait for 5 workers and farmers. The peacock raced up the slope, everyone was surprised to see papaya, avocado trees on both sides of the road, forming a beautiful green patch, pressed against the dark gray pumice area. And the farmers themselves still see the mystery, in the fields and fields, there are only rocks and stones, yet the orchards are still green for bountiful crops. People forget the fatigue of the heat, find the heaven and earth here strangely enchanting. The hustle and bustle of life gradually subsided, in front of my eyes, thousands of colors flickered back and forth around the foot of the mountain, which was quiet and immense. This land for many years has been deposited by alluvium, now becoming the most fertile place of Choah village. The Krong No River builds up from the water to the products on both sides of the river, giving the local people a warm and friendly atmosphere, amidst the vastness of heaven and earth. The legendary story of A Tay and A Yong is told by the village elders over a jar of yeast that has been handed down for generations. That, their love was hindered because the girl’s house was too poor, there was no gift to bring the boy back to be her husband. The desperate couple threw themselves into the river to die. The girl turns into Krong Ana river (mother river), boy turns into Krong No river (father river). The Serepok River is the eternal blend of faithful love. The river has nurtured and created a culture unlike any other. While here there is a revelation of wonder that fascinates all mankind. The Mystery of the Bat Cave The vehicle carrying the group stopped in the middle of the orchard, next to the people’s farm huts. Weaving through the fruit-laden lychee orchard, we walked more than a kilometer on jagged pumice paths, frozen by the molten lava spewing out of the crater. The feet quickly reached the basalt field stretching as far as the eye could see. People seem to be trapped in the vast windy space, the fatigue is somewhat reduced. Touching the lava rock shelf where the new cave was discovered, each stone surrounded a giant arch. Following the flash of a flashlight, we groped on the jagged rock and entered the nearly 1 km long cave. In the dark and deep recesses of the cave, the smell of dampness penetrated the nostrils. The cool world inside the cave dispels the hot air outside. Flashlight streaks quickly glide over countless stalactites, traces of a volcano that have fallen asleep, making everyone stunned. The cave we are exploring, the experience is the newly discovered cave. Indigenous people say that there are many caves around this area, including bats, which is not strange. Before knowing Chu Bluk cave, the people around here used to call it Bat cave. If there are tourists to visit, these caves are not the first place they introduce, because of the wildness, difficult-to-find location, undeveloped services. Therefore, this has contributed to preserving the original purity of the cave until now. Leaving the cave, the sunset is long. On the Krong No river, the bobbing boats of the fishermen cast their nets and cast fishing lines. The woman showed off a 3kg trout struggling in her hand, returning down the stream after releasing the spoils. From time to time, motorboats carrying sand tore through the water, making the river’s surface agitated. Then, momentarily right there, the river was calm and calm again… The volcanic cave system in Krong No district, Dak Nong province is a 25km-long volcanic cave system in basalt, stretching from the crater of Buon Choah along the length of the Serepok River to the area of ​​Dray Sap waterfall. Dak Nong Geopark was recognized by UNESCO as a global geopark in 2020, contributing to strongly promoting tourism and attracting domestic and foreign tourists to explore. This is the third global geopark in Vietnam.

(Photo: Internet) This mountain has a gentle slope and is not too high, only 580m but this is an inactive volcano. In the summer, this place is covered with green trees and in the snowy winters, this mountain is covered with pure white snow. (Photo: Internet) (Photo: Internet) (Photo: Internet) To get to the top of Omuro, you need to take a cable car with a ticket price of 700 yen (about 150,000 VND) for adults and 350 yen (about 75,000 VND) for children. You can walk around the crater and enjoy the panoramic view of the entire Izu peninsula. On a clear day, you can see Mount Fuji, Oshima Island – the closest large island in the 7 islands of the Izu island chain. The beautiful scenery here will make visitors dazed for a while. (Photo: Internet) (Photo: Internet) If you’d rather experience more than just walking and taking in the beautiful scenery, you can climb down to Omuro crater and hone your archery skills. You may not believe it, but inside this mountain that once spewed fire, lava, limestone and ash is now an archery field. You only need to pay 1,000 yen (more than 200,000 VND) for an hour, including rental fees for bows, bows, gloves and training fees from the staff of the shooting range. An equally fascinating experience for adventurers is paragliding down the slopes of Mount Omuro. (Photo: Internet) After enjoying all the fun on the mountain, you can visit the Izu Shaboten Zoo, which has many cacti, other plants and a large petting zoo. (Photo: Internet) Another place at the foot of Mount Omuro that is very suitable for creating good check-in photos is the Omuro Yamazakura-no-Sato cherry blossom viewing spot. These cherry trees are called jugatsu zakura, which means “October cherry blossoms”. (Photo: Internet) Flowers start to bloom in mid-September and various flowers bloom until early May. Since not everyone can come to Japan in spring, the prime time for cherry blossom viewing and part of the culture. the land of the rising sun, so this is a great choice. Mount Omuro is the perfect backdrop for this beautiful painting of cherry blossoms in full bloom.

Photographs taken on Mars show many glaciers-like features in Antarctica, If these covered glaciers do, in fact, exist, they could be a reason to direct future crews to Mars towards this area. The location was inherently attractive to SpaceX and NASA because it was a wide, flat plain, ideal for landing spacecraft. If there is ice that is not too deep below the surface, the astronauts can also easily have water within reach. Lead researcher Shannon Hibbard, a graduate student at the University of Western Ontario, Canada, said the newly discovered flow-like characteristics are very strange because they appear on flat terrain. “There is a lot of evidence that this is an area with a lot of ice, but we don’t have any confidence that there could be a glacier in places with winding features,” Hibbard said. this. They exist in a fairly flat plane, so that’s weird. ” Mysterious terrain Arcadia Planitia is located in the lowlands north of Mars. In the past 3 billion years, lava flows have been active in this area, so it is much less prone to cracking with craters than in other areas on the planet. Data collected from orbit over many years show that the ground in the area is rich in hydrogen. Because water is made up of molecules of hydrogen and oxygen, this hydrogen shows the presence of ice just below the surface. For decades, scientists have found features on Mars to be related to ice. Along the low hills, there are debris that look like a glacier flow covered in a thin layer of rock. There are also patterns in gulls that look similar to glaciers that flow through valleys on Earth. Similar features occur in Arcadia Planitia, Hibbard said. Lobate features occur near a set of mountains called Montes Erebus that rise up from the plain. Orbital images, thermal data showing surface temperature during day and night, albedo data showing surface reflectivity, dust cover information and altitude data, and topographic. Glacial flow The winding features are a big mystery, Hibbard says, because they look like they were created by the flow of ice, but the topography is not steep enough to explain why the meteor was moving. “We had to try to figure out what they are, why they have thermal symbols, why they are so bright day and night, why they have flow characteristics, why Are they threaded again? ”she said. The analysis showed that these traits were in fact derived from ice. The curled shapes look similar to other features related to slow-flowing matter seen on Mars, Hibbard said, and the data shows these points actually contain a lot of ice. The most similar sinusoidal feature, Hibbard says, is the currents inside the Earth’s ice sheets, which mainly occur in Antarctica. These faster moving ice currents are not well understood on Earth, much less than Mars, but they do show an example of ice flowing in fairly flat terrain, Hibbard says. This is a controversial claim, Hibbard says, because most ice currents on Earth need at least a thin layer of liquid water at their bottom to lubricate their flow. It is unclear whether sub-ice water existed or existed on Mars, she said, and it is not clear if a wet background is needed to create ice currents on the Red Planet. One possibility might be that in the past, when Mars’ orbit was tilted differently than it is today and its climate was different, melting under ice may have occurred. This research was published in the May issue of the journal Icarus.

Gara Medouar reappeared in the 2001 sequel ‘The Mummy Return’ in 2001. The eerie location then becomes the wicked lair of 007 Bond character Franz Oberhauser in the 2015 Specter film Oberhauser His cave is located inside a crater, but in reality, Gara Medouar is a crater. Gara Medouar, which in the local language means “round mountain”, is the remains of a large mass of limestone that has been eroded away. The current state is 50 meters higher than the desert, about 50 hectares in area. The central region collapsed, forming a valley. The partially broken circular mountain mass creates a central entrance. The bizarre crater attracts tourists in Morocco The interior was quite flat and probably because the water had washed away all the material long ago. The unique irregular terrain of the Gara Medouar makes it a very impressive natural haven. Many caravans choose this area to hide when they encounter a sandstorm during their desert journey. Later, at a time Gara Medouar became a temporary detention area for slaves sold from Africa to Portugal. In the 11th century, it developed into a fortress capable of protecting the nearby commercial city of Sijilmasa, where gold coins were minted and trade routes from the south. The defensive wall, built around a third of the mountain’s natural circumference, is currently the remains of the fortress. But the most impressive is the wall straight through the large ravine blocking the only entrance to the mountain. The wall was about 8 meters high, some were 12 meters long and 80 meters long and 4 meters thick. The wall has an extremely solid structure, limestone blocks bound together by lime mortar. The fortress with high ground is well protected, providing extensive control, from the height of the Gara Medouar, one can observe the area with a radius of up to 50 km. After Gara Medouar appeared in the famous movie ‘The Mummy’, the site became more and more popular, attracting many tourists. However, tourism activities also disrupt archaeological investigations.
