Nine wonders of world-class scenic spots

1. The Great Blue Cave in Belize: It is located at the edge of the submarine plateau of the Grand Bahama Shoal in the Caribbean, 60 miles away from Belize City. It is the largest ocean blue cave found in the world so far, with a perfect circle shape, a diameter of over 305 meters and a depth of 123 meters. The entrance is surrounded by two coral reefs, and the whole cave looks dark blue because of the deep water.

2. Danajir Depression: Located in the northeast of Ethiopia and the east of Eritrea, the northernmost part of the East African Rift Valley, with an altitude of only 100 meters, is one of the lowest points in the world. Many volcanoes are buried under thousands of meters of salt, which is called the most cruel place on earth. Colorful springs on the ground and strange spray holes on saline soil have created a unique and gorgeous landscape.

3. Mendenhall Ice Cave: Juneau, Alaska, USA, also known as Juno Ice Cave, is located under the Mendenhall Glacier. When you walk past it, you will find it is melting. Inside is a very narrow ice cave, and the sunlight reflected from the hole illuminates the cave wall. The dark blue transparent zenith we see is completely composed of glaciers.

4. Eye of the Sahara: Mauritania, located in the southwest of the Sahara Desert in Africa, with a diameter of 48 kilometers, can be clearly seen from space. At first, people thought it was formed by the collision of meteorites. At present, geologists think it may be caused by uplift or erosion of geological structure. The formation of this circular appearance is still a mystery. I think it's probably an alien!

5. Ige Natural Well in Mexico: Located in Yucatan Peninsula, Mexico, lush vegetation covers the wellhead, and vines of many tropical plants hang on the well, with a depth of about 335 meters. It is a world-famous karst collapse pit. It is said that this place used to be a place for the Maya royal family to rest or celebrate holidays, and now it has become one of the most famous tourist attractions in Mexico.

6. American Grand Prism Hot Spring: Located in Yellowstone National Park, it is about 75 to 965,438+0 meters wide and about 49 meters deep. It will eject about 2,000 liters of groundwater every minute and the temperature is about 765,438+0℃. It is the largest hot spring in the United States and the third largest hot spring in the world. Colors change with the seasons. Spring is bright orange red, summer is orange, red or yellow, and winter is dark green.

7. Mexico Giant Crystal Cave: Located 290 meters underground in the Nega Mountains in the Chihuahua Desert, the cave is full of spectacular luminous giant stone pillars. In 2000, two miners named Peoles Industries discovered this strange cave while digging an underground tunnel. There is the largest crystal in the world in the cave, which is 1 1 m long and weighs 55 tons.

8. Dawaza Flame Pit: Dawaza, located in Turkmenistan, was accidentally discovered by Soviet geologists while drilling 197 1 years ago. A piece of soil under the drilling device collapsed, leaving a big hole with a diameter of about 50- 100 meters. In order to prevent toxic gas from leaking out, they decided to ignite the leaked natural gas. As of 20 16, the flame of this cave has never stopped, and the locals call it the gate of hell.

9. Waitomo Firefly Cave: Located in the Waitomo Cave Area in Waikato, New Zealand, the underground limestone layer constitutes a series of huge cave systems, dotted with various stalactites, stalagmites and fireflies. Thousands of fireflies shine brightly in caves. Some people call this natural wonder "the ninth wonder of the world".
