Covering 2.2 million acres, Yellowstone National Park is a geographic behemoth and, as the birthplace of America’s national park system, a cultural giant as well. But since its official establishment in 1872, the bucolic lands have been the source of frequent conflict: between Native Americans and Europeans, and tourism and environmental conservation. In this episode, prizewinning author Randall K. Wilson explores the complex history of the park, from its geological roots to its role in our understanding of the environment and our nation as a whole.
