Since its beginning in 1872, Yellowstone National Park has been an alluring destination with significance beyond its stunning mountain scenery, abundant wildlife, and the world's largest collection of geysers and hot springs. Once deemed America's "wonderland," this national park has long been a repository of meanings for and aspirations of the American people. In Sacred Wonderland Thomas S. Bremer explores the historical role of religion in making Yellowstone National Park an American icon. The park's religious history spans nineteenth-century evangelical Christian ideas of Manifest Destiny in addition to religiously informed conservationist movements. Bremer touches on white supremacist interpretations of the park in the early twentieth century and a controversial new religious movement that arrived on the scene in the 1980s. From early assumptions about Native American beliefs to eclectic New Age associations, from early rivalries between nineteenth-century Protestants and Catholics to twentieth-century ecumenical cooperation, religion has been woven into the cultural fabric of Yellowstone. Bremer reveals a range of religious beliefs, practices, and interpretations that have contributed to making the park an appealing tourist destination and a significant icon of the American nation.
