The unusual World "Door to Hell" and "Crystal Cave"

Yes, places like these two do exist in our planet. "Door to Hell and "Crystal Cave"

The Naica Crystal Cave is indeed like different planet, it reminded me of the Superman movie where Clark Kent talked to his father.  

The Crystal Cave is located 300 metres (980 ft) below the surface in Naica, Chihuahua, Mexico. The cave contains giant selenite crystals as large as 4 feet (1.2 m) in diameter and 50 feet (15 m) long. The cave is extremely hot reaching up to 58 °C (136 °F), which means that overstaying in the cave without proper gear is impossible.

Door to Hell 

 

Darvaza Gas Crater at Night with Silhouettes of People toasting wallows. Lol

Located in Darvaza sometimes referred as Derweze, Turkmenistan. In 1971, geologists tapped natural gas in a cavern, while drilling the ground collapsed leaving a large hole with a diameter of about 70 metres (230 ft). To avoid any poisonous gas discharge, it was decided to lit the crater on fire so as not to any further accident due to the gas fumes. And from that day on, the crater has been burning ever since.
