Mountain Time: A Field Guide to Astonishment is an essay collection that explores the inner and outer natures of remarkable human and nonhuman beings. It is a book about paying attention—with the mind and with the heart. The essays confront the ethical and personal challenges Renata Golden faced in a harsh and isolated environment and examine the power of nature to influence her understanding of the human spirit. The lessons she learned on the borders of Arizona, New Mexico, and Mexico jolted her out of her customary way of seeing the world—which is the transformative power of a thin place, where the borders between the sublime and the profane melt away. The essays call attention to the animals that are often shunned—pack rats, rattlesnakes, ants, prairie dogs, and other desert dwellers that some consider better dead than alive. Manyof the animals in these essays are at risk of extinction. The essays honor these animals for the role they play in the wild world and for their unique abilities, such as cooperative societies and complex language skills. By recognizing the animals’ value, Golden gives readers reasons to be moved to save them, if it’s not too late.
