Explore it. The USA

In fact, this is a whole cave system, which is considered to be the longest in the world, so if the speleologist is drowsy in you – here. To the mammoths, this cave, which appeared as much as 10 million years ago, has no relation – this name appeared due to the play of words in the English language, according to which one of the meanings of the word «mammoth» is huge. Earlier on the underground river Echo, which is located on one of the lower levels, excursions were conducted on boats, but now this practice is a thing of the past. Although this underground kingdom may seem somewhat eerie, it definitely has a unique beauty. 5. FLY GEYSER Fly is a geyser that has become one of the most famous in the world, despite the rather small height, which jets of water rises (it is only 1.5 meters). The geyser is surrounded by very beautiful stone formations, the color of which, due to mineral layers and algae, is very unusual, and represents a single natural ensemble. 6. LAKE CASCO Lake Caddo Texas Considering the photos of this unusual lake, you might think that it is straight from a mystical film – it has such an unusual atmosphere. The labyrinth of the channel, surrounded by rare Arizona cypresses, attracts travelers: when going for a walk along this water system, it is worthwhile to be cautious, because sometimes people are lost here (however, they are found alive and unharmed). At first sight, because of the countless number of water lilies and covered with duckweed lawns, Caddo resembles a swamp, but the water here is clean and fresh, and the natural complex is very beautiful.

7. THE SCREEN LAKE This lake is the deepest in the United States, and its distinctive feature is the perfect round shape. Its presence is explained by the fact that the lake is located in the crater of an inactive volcano, which, however, can not be called completely extinct. 8. THE WHITE DESERT From other deserts, this is distinguished by an amazing white color – because almost entirely this area consists not of sand, but of… gypsum! There are very few gypsum deserts in the world, and White can be rightfully considered one of the most beautiful. 9. THE LENGTH OF MONUMENTS In this valley, not one miracle of nature is collected, but many miraculous monuments, so similar to the bizarre castles and unearthly structures of stone. They appeared due to a change in the landscape – when there was a sea, at the bottom of which slate accumulated, but after a sharp change in the earth’s crust, land was formed instead of water, and with it intricate stone figures over which sand, wind and precipitation work. 10. THE ETERNAL RAINBOW This rainbow does not appear after the rain – it is carved from stone, and has been on the American soil for many, many years. For the Navajo Indians, it was a sacred place, and they can be understood. The wide stone bridge really shimmers with all the colors of the rainbow, representing an unforgettable sight.
