Evidence of one of these explosions is called Ubehebe Crater. The explosion left a huge hole in the ground almost a kilometer and a half wide.
In many areas of Death Valley it is easy to see where the ground has been pushed up violently by movement deep in the Earth. This movement has created unusual and beautiful rock formations. Some are red. Others are dark brown, gray, yellow or black.
Other areas of rock look as if some huge creature violently broke and twisted the Earth to create unusual, sometimes frightening shapes.
In other parts of Death Valley there are lines in the rock that show clearly that this area was deep under an ocean for many thousands of years. Much of the Valley is flat and extremely dry. In fact, scientists believe it is the driest place in the United States. In some areas the ground is nothing but salt. Nothing grows in this salted ground.
PHEOBE ZIMMERMAN: However, it would be wrong to think that nothing lives in Death Valley. The Valley is fully of life. Wild flowers grow very quickly after a little rain. Some desert plants can send their roots down more than eighteen meters to reach water deep in the ground.
Many kinds of birds live in Death Valley. So do mammals and reptiles. You might see the small dog-like animal called the coyote or wild sheep called bighorns. Other animals include the desert jackrabbit, the desert tortoise or turtle and a large reptile called a chuckwalla. Many kinds of snakes live in the Valley, including one called the sidewinder rattlesnake. It is an extremely poisonous snake with long sharp teeth called fangs.
