Throughout history, humans have sought creation stories to define our identity and affirm our connections with the universe, diverse life forms, and one another. Over the last two centuries, science has delivered a bold new creation story full of immense time and space, extraordinary objects, and powerful natural forces. Science ideas can seem mere abstractions, but at the Grand Canyon, better than anywhere else on Earth, our new creation story is manifested physically and powerfully. A major work of literary nature writing, Canyon and Cosmos takes readers on a journey through the Grand Canyon's deep time, geological forces, and biological evolution, making them very real, personal, and meaningful. Through decades of hiking and kayaking, author Don Lago has gotten to know the canyon intimately. Ranging through world mythologies and Native American spirituality, he explores how humans have sought to understand the universe. He confronts existential questions of whether humans can find enough meaning in the scientific cosmos. Through poetic prose, symbolism, and philosophical insight, he shows how existence itself is our deepest source of life and meaning.
