What is the genre of Desert Solitaire?

Desert Solitaire: A Season in the Wilderness is a master piece of non-fiction by American writer Edward Abbey, originally published in 1968. Abbey uses this book as a platform not only to make observations about the geography, fauna and flora of Utah, but as a place to vent his spleen at the destruction of the natural world, and the dehumanizing nature of our society. The book is also filled with humor, pathos, and great sensitivity. His prose is elastic, conversational at some points, poetic and profound at others. A Season in the Wilderness by Edward Abbey has a much deserved reputation of being one of the finest book written about the American West. Abbey spent time as a park ranger in Arches National Park in the late 60s, and in the process, traveled all around southern Utah and northern Arizona. This book is the outcome of that stay, yet it is so much more.
