An exquisite portfolio and guide to America's most popular national park. Yellowstone National Park welcomes three million visitors every year. Most are drawn to its eye-popping hydrothermal features, including the world-famous Old Faithful. The region famously sits over a continental "hot spot," a chamber of molten magma several miles below the surface that heats the groundwater and powers the park's geysers, hot springs, mud pots and steam vents. A network of paved roads and boardwalks offers visitors easy access to the kaleidoscopic colors and dramatic eruptions of some of the park's impressive waterworks. However, few tourists experience the stunning all-season splendor of Yellowstone's backcountry, which is home to wonders that, on their own, would have easily justified the park's creation. This book captures the perennial delights of Yellowstone's most popular features, but it also introduces readers to the park's vast swaths of grasslands, wetlands, rivers, waterfalls, valleys and mountain peaks, its richly diverse plant life and its free-ranging wildlife, including the newly reintroduced wolves.
