Yellowstone National Park, established by the U.S. Congress as a national park on March 1, 1872, is located primarily in the U.S. state of Wyoming, though it also extends into Montana and Idaho. The park was the first of its kind, and is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park.
Grand Teton National Park is a United States National Park located in northwestern Wyoming, south of Yellowstone National Park. The park is named after the Grand Teton, which, at 13,770 feet (4,197 m), is the tallest mountain in the Teton Range. The name "Tetons" originally was intended to describe several hills near the town of Arco, Idaho. They were named by a French trapper who thought that they resembled the female body. (Ergo tétons, the French word for "nipples" or "teats".) Many years later the name was mistakenly applied to the mountains of present day Grand Teton National Park due to the poor map-making and map-reading standards of the time. Grand Teton National Park was established on February 26, 1929.
