Continuing our series on the U.S. National Parks, this week we feature Yellowstone National Park. Yellowstone was declared a national park on March 1, 1872, the first to receive the designation by Congress. Named after the Yellowstone River that runs through the park in the northwest corner of Montana, Yellowstone is probably best known as the home of "Old Faithful," a geyser that erupts on average every 90 minutes, sending boiling hot water and steam 184 feet into the air.
According to the park website, "Yellowstone was set aside as the world's first national park because of its hydrothermal wonders. The park contains more than 10,000 thermal features, including the world's greatest concentration of geysers as well as hot springs, mud pots, and steam vents." Yellowstone is also home to a variety of wildlife, including large herds of bison which roam the Park freely, unfettered by fences. Bison are plentiful enough that visitors to the park are virtually guaranteed to see them during their visit. To learn more about this great park, click here.
