"There is a wilderness where waterfalls plunge down rocky cliffs, herds of bison graze on sweeping grasslands, and forests ring with the howls of wolves. A place where mud bubbles, springs steam, and water explodes from deep underground. People have been drawn to this landscape for thousands of years and now it's your turn to explore...Welcome to Yellowstone."--Page 4 of cover.
