What magical experiences did you have during your trip? Or a sudden coincidence?

Turkmenistan has a 70-meter-wide crater that has been burning. According to local residents, this crater has been burning for 35 years, and it is also called the Gate of Hell. 197 1 year, a geologist accidentally discovered a huge cave while drilling a natural gas deposit. All the caves collapsed and all the equipment and camps were destroyed. Because the cave is full of toxic gas, I hope it can be burned in a few days in order to prevent it from being ignited. Unfortunately, I didn't do it.

Luolai Mashan is a tabletop mountain surrounded by a 400-meter cliff. It rains every day at the top of the mountain, because it will wash away many nutrients needed for plant growth, so nothing grows and looks bare, but it forms a unique landscape. Roraima Mountain has also created the edge of some of the highest waterfalls in the world, which is quite remarkable.

The popular craters in America are amazing. You would never think that this crater hit the plain at a speed of several kilometers per second about 50 thousand years ago, leaving a huge crater. 50,000 years ago, this area was still a vast open grassland. There may not be humans, but there are woolly mammoths and camels.

The big hills in Europe are not what people think. They are not deserts, but they are magical and formed in forests. Dune is a famous paragliding site, and the top provides spectacular scenery, and you can clearly see the open sea and forest.

B- 15 iceberg is probably the largest iceberg ever, bigger than Jamaica Island. In 2003, it cracked, and one of the larger fragments drifted northward, and was finally installed as a glacier in 2005, which directly led to the rewriting of many Antarctic maps.
