Yellowstone National Park occupies 3,468 square miles that are mostly within the state of Wyoming but extend into eastern Idaho and southern Montana. The area is part of the Snake River Valley that lies south of Mammoth Springs along the Continental Divide and sits atop the Yellowstone Plateau, which is surrounded on all sides by various mountain ranges known as the Middle Rockies.
The John D. Rockefeller Jr. Memorial Highway connects the two parks, which, along with the surrounding forests, form the 18-million-acre area known as the Greater Yellowstone ecosystem. The ecosystem is one of the largest undisturbed temperate region ecosystems in the world and remained largely unexplored until the latter half of the 19th century. This seismically active region lies above the Teton fault, experiencing thousands of earthquakes each year and forming the largest volcanic system in North America.Learn more about Maps & Cartography
