In honor of the 50th anniversary of the Wilderness Act, BackStory heads into the wilderness, exploring Americans’ fascination with, and fear of, wild places – and the ways in which humans have impacted even the most remote corners of the country. From early English colonists who saw wilderness in an already settled land, to 19th and 20th century Americans who sought to flee cities and find peace in nature, we’re taking a look at how our physical and mental landscapes have changed over time.
