Dead vlei is a white clay pan located near the more famous salt pan of Sossusvlei, inside the Namib-Naukluft Park in Namibia. Dead Vlei has been claimed to be surrounded by the highest sand dunes in the world, the highest reaching 300–400 meters which rest on a sandstone terrace.
The clay pan was formed after rainfall, when the Tsauchab river flooded, creating temporary shallow pools where the abundance of water allowed camel thorn trees to grow. When the climate changed, drought hit the area, and sand dunes encroached on the pan, which blocked the river from the area.

The trees died, as there no longer was enough water to survive. The remaining skeletons of the trees, which are believed to have died 600–700 years ago, are now black because the intense sun has scorched them. Though not petrified, the wood does not decompose because it is so dry.

Lake Baikal, meaning, in Mongolian, “the Nature Lake”, is a rift lake located in southern Siberia, Russia. It’s at least 20 million years old, and roughly a mile deep at its lowest point. The Siberian lake is the largest freshwater lake by volume in the world and is considered the world’s oldest lake. The lake is completely surrounded by mountains and is fed by as many as 330 inflowing rivers. During ice season, that starts usually in mid-January and lasts till mid-April., ice depth increases up to 140 centimeters, that allows quite safe vehicle driving on ice cover. The ice itself is very picturesque because of transparency of 1 meter depth, having different patterns of crevasses and bubbles, performing astonishing sounds.

Remarkable Rocks in Flinders Chase National Park, located at the west end of Kangaroo Island,  Australia,  is island’s signature landmarks. These rocks are the remains of an igneous intrusion that has since been weathered down into an array of bizarre boulders, sculpted by wind and rain over the course of many thousands of years. Continuous wind erosion in a relatively dry climate can result in such bizarre shapes.
