The wonders of American national parks
1. In the Capitol Reef National Park in Utah you can see lots of beautiful cliffs and rocks. Many of them are covered with rock drawings and paintings. They were made by the Fremont Indians, who lived there two thousand years ago and mysteriously disappeared.
2. The Hawaii Volcanoes National Park has two of the world's most active volcanoes. The true character of the park is best discovered on foot. You can walk along the paths, of hard lava and often you can take a photo of real flowing lava running down the volcano slope (склон)! But don't worry, the park rangers won't let you get too close.
3. The Grand Canyon in Arizona is one of the true natural wonders of the world. It makes most of the Grand Canyon National Park and million of tourists visit it every year. The Grand Canyon is over 320 km long and up to 6 km deep. The top and the bottom of the canyon have very different weather and vegetation (растительность). While it is very hot at the top, it can be very cold at the bottom, especially at night. There are signs that people lived in the Grand Canyon 4,000 years ago.
4. The Yellowstone National Park is the first and the oldest national park in the USA. It was founded in 1872. Now it is home to a large variety of wildlife including grizzly bears, wolves, bison, and elk. It's famous for its geysers and hot springs (источники). The most famous geyser shoots hot water and steam (пap) regularly — once every 75 minutes. The water is hot enough for cooking.
5. Going to Death Valley was very dangerous. It's the hottest place in the United States and summer temperature can go up to 54 degrees! Today, Death Valley is a national park In the 1800s people came here looking for gold and silver, but the terrible heat made them leave the place. Today, you can visit these ghost towns and look inside old houses, prisons and banks to see how people lived then. But don’t forget about the heat!
