The first national park of U.S., Yellowstone National Park is known for its wildlife. The park is home to hot springs and geysers. Yellowstone National Park covers canyons, rivers, and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes. Half of the world's geysers and hydrothermal features are in Yellowstone, fueled by ongoing volcanism. During the winter, visitors can experience snow-covered landscapes.
