America’s Most Incredible National Parks: Yellowstone
Yellowstone National Park became the first national park in the U.S. when it was established in 1872. Many Americans consider it the quintessential American national park; its highlights include Old Faithful geyser, hot springs, the Grand Canyon of Yellowstone, and wildlife such as grizzlies, wolves, elk and bison. The park, spanning across parts of Wyoming, Montana and Idaho, boasts about 10,000 hydrothermal features — half of the ones that exist in the world — among them 300 geysers.
