Refuge: An Unnatural History of Family and Place is a book-length essay by environmentalist Terry Tempest Williams. This book explores the relationship between the natural and unnatural along with condemning the American government for testing nuclear weapons in the West. Williams uses components of nature such as the flooding of the Great Salt Lake and the resulting dwindling populations of birds at Bear River Migratory Bird Refuge to illustrate the importance of nature preservation, acceptance of change, and the impact of human intervention on the natural world.
