For those looking forward to exploring natural wonders, we will present four natural wonders in the US that we believe are worth visiting.
Death Valley National Park
It is the lowest, hottest, and driest part of North America. The hottest summer on record in the valley saw temperatures top 120.F on 40 days. Ground temperatures as high as as 201.F have been reported. Still, Death Valley is called with the wrong words. There are areas that are friendly to plants and animals. Death Valleys＂walking＂rocks move on their own as a result of freezing and thawing(融化).
Yellowstone National Park
Yellowstone's Old Faithful Geyser is powered by an underground super volcano. In 1872 Yellowstone became the world's first national park. The park's wildlife includes bison, bears, and hundreds of other animals.
Crater(坑) of Diamonds(钻石) State Park
Discovered in Crater of Diamonds State Park，the 40-carat is the largest diamond ever found in the US. The diamonds and the crater are by-products of a volcanic eruption. Visitors can search the 37- acre site for diamonds and if you find it you keep it.
Hawaii Volcanoes National Park
