Greater Yellowstone Ecosystem
The Greater Yellowstone Ecosystem (GYE) is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. It is located within the northern Rocky Mountains, in areas of northwestern Wyoming, southwestern Montana, and eastern Idaho, and is about 22 million acres (89,000 km2). Yellowstone National Park and the Yellowstone Caldera 'hotspot' are within it.
