Don Lago is the author of Canyon and Cosmos: Searching for Human Identity in the Grand Canyon (University of Nevada Press, 2025), which uses the Grand Canyon as a Walden Pond for exploring the place of humans in the grand scheme of things. It includes Native American spirituality, as several tribes regard the canyon as their place of origin. He is also the author of other book of literary nature writing, including Where the Sky Touched the Earth: The Cosmological Landscapes of the Southwest, which holds a Monument Valley sunrise on the cover. He lives in a cabin in the forest outside Flagstaff, Arizona.
