The South Central Rocky Forest ecoregion extends into the states of Wyoming, Idaho, and Montana. The portion of the ecosystem that extends to these states is called Yellowstone National Park.
IT IS THOUGHT TO BE THE FIRST NATIONAL PARK IN THE WORLD. IT WAS ESTABLISHED BY THE U.S. CONGRESS AND SIGNED INTO LAW BY PRESIDENT ULYSSES S. GRANT ON MARCH 1, 1872.
THE PARK IS HOME TO ONE OF THE LARGEST HIGH ALTITUDE LAKES IN NORTH AMERICA - THE YELLOWSTONE LAKE. APPARENTLY, THE LAKE IS PERCHED ON YELLOWSTONE CALDERA, THE LARGEST SUPER VOLCANO ON THE CONTINENT
ABOUT HALF OF THE WORLD'S GEOTHERMAL FEATURES ARE FOUND IN THE YELLOWSTONE NATIONAL PARK - MOSTLY FUELED BY THE VOLCANIC ERUPTIONS OF THE YELLOWSTONE CALDERA
