There is nowhere in North America more iconic than Yellowstone National Park. Towering mountains, spewing geysers, vast forests and valleys harboring the highest megafauna density on the continent make this a must-visit destination for anyone wanting to experience the classic American West. But the Greater Yellowstone Ecosystem, as it is known by locals and researchers, is much more than what is found within the National Park’s borders, despite its enormous size. The ecosystem includes huge, pristine prairies, alpine crags and meadows, near-arid desert, and the most diverse and lovely scenery one could hope for.
