Yellowstone, America's first national park, covers more than 3,400 square miles and is widely known as the home of the Old Faithful geyser, grizzly bears, and the bald eagle. Its unique landscape, shaped hundreds of thousands of years ago by supervolcanos and glacial melting, includes natural wonders like steam vents, colorful hot spring pools, canyons, and towering waterfalls. Author David Aretha tells the fascinating tale of the park's history and the variety of wildlife found in the park, including elk, bison, moose and gray wolves. Coverage of controversies such as snowmobile access and wolf management efforts is included, as well as a full inventory of visitor attractions.
