Natural world wonders
1. Spread over 135 square miles in Yunnan province, the Shilin Forest looks like an ancient petrified forest filled with rock formations that jut vertically from the ground. Geologists say Shilin Stone Forest was formed 270 million years ago, when the constant movement of the earth caused the waters of the large sea, which covered the area, to retreat and allowed the limestone cliffs to rise.
2. The Darvaza gas crater, known as «The Door to Hell», is a 196 feet wide and 65 feet deep hole in the Karakum desert in Turkmenistan. The fire, fueled by natural gas, has been burning for the last 42 years, not by a natural occurrence, but instead, as a result of a Soviet gas exploration accident. Geologists accidentally tapped into a massive underground natural gas cavern, causing the ground to collapse and the entire drilling rig to fall in.
3. Also known as «The Great Blue Hole», the Belize Barrier Reef is one of largest barrier reefs in the world. It creates a natural ecosystem that includes atolls, several hundred sand cays, mangrove forests, coastal lagoons and estuaries. It’s so vast that much of it remains undiscovered and only 10 per cent of the marine life on this reef has been identified.
