The name "Yellowstone" may have a backyard familiarity, but 90 percent of the national park's 2 million acres (800,000 hectares) is barely touched and holds much more than what most people see. It's a giant swatch of terrain—much of it remote, some of it dangerous—but all of it commands awe and respect. Wolves, bison, and bears roam freely. An incredible 300 waterfalls have been documented in recent years, and for the intrepid explorer, there awaits life-changing encounters with the natural world. We'll take you off the road and beyond the hot tourist spots to see hidden valleys and a 20-mile-long (32-kilometer-long) canyon, in a Yellowstone you don't know.
