The nature of the animal world is mainly determined by climatic conditions and vegetation. In broadleaf forests, black bears (baribals) and grizzly bears, virgin deer, red lynx, cougar, possums, skunks, chipmunks are common. In mixed forests live brown bears, lynxes, martens and wolverines. Alaskans arrange seals and walrus rookeries. In the steppes, in addition to large artiodactyls (bison, deer, vilorogie antelope, thick-legged sheep), there are foxes, coyotes, badgers, ferrets. Bison was mercilessly exterminated by man for the sake of valuable skins, but at present they are under the protection of the law. Deserts are inhabited mainly by small mammals (marsupials, etc.), reptiles (snakes, lizards, iguanas), as well as insects (scorpions, spiders, etc.). In the tropical forests of the Gulf Coast there are crocodiles and alligators, as well as anteaters, porcupines and marmosets. In the reservoirs live nutria, muskrats, beavers, as well as amphibians – frogs, toads, newts.

Birds living in the United States are very diverse. In the middle latitudes you can observe owls, vultures, eagles, mockingbirds, cranes, snipe, peregrine falcon, cormorants. In the south of the country there are more exotic species – parrots, flamingos, pelicans, hummingbirds.

The fish world is mainly represented by salmonids – only in the Yellowstone reserve are 18 species. Near the Hawaiian Islands, 600 species of tropical fish adjoin the turtles.

Save a huge species diversity of the animal kingdom of the United States help the extensive national parks and reserves. The largest species diversity of mammals, birds, fish and insects can be found in the national parks of Yellowstone, Everglades, Zion (about 300 bird species), Bryce Canyon (60 mammal species and 160 bird species), Santa Ana (the largest bird sanctuary). In the world-famous Yellowstone Reserve, the largest populations of bison, grizzly bears, pumas and wolverines have been preserved. In the Everglades National Park, where tropical marshes are preserved, there are co-existing Mississippian alligators and sharply crocodiles, as well as numerous bird species, including exotic ones.

1. GRAND CANYON

One of the most unusual, deep and beautiful canyons of the world more than deserves a visit. It is located on the territory of the National Park of the same name in Arizona and attracts about 4 million tourists every year. We recommend climbing the observation deck «Grand Canyon Skywalk», which provides an excellent overview of this natural wonder – not least thanks to the glass floor. The main thing – not to dizzy, because the depth of the canyon in some places reaches 1800 meters.

2. NIAGARA WATERFALL

One of the most beautiful and majestic waterfalls in the world is a must on the list of «must see» American natural attractions. There is nothing to talk about here, because this is a beautiful sight to see with your own eyes.

3. THE DEATH OF DEATH

The place is not for the faint-hearted, and it’s not just a rather ominous name. This is an incredibly hot place, where the highest temperature in the world was recorded at one time, so it’s better to plan a visit to the Valley from November to February, when it’s cooler here. It is here that the famous Moving Stones are located, in addition, thanks to a truly alien landscape, here were shot episodes of many films, including the fourth part of the «Star Wars».

4. THE MAMMONT CAVE

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.
