ellowstone National Park in Wyoming, the USA, is one of the most geothermically active regions in the planet. Half of the world's all geothermal features are located here. The park spanning an area of nearly 9000 square km comprises of 10,000 geysers, hot springs, mud pots, and fumaroles, thanks to its location in an ancient active caldera. Yellowstone itself is one massive super volcano that erupted with tremendous force several times in the last two million years. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining, nearly intact ecosystem in the Earth's northern temperate zone.
