Leave it as It Is is the most engaging and powerful book about Western public lands that I have read in a long time. Gessner published a terrific book in 2015 titled All the Wild That Remains: Edward Abbey, Wallace Stegner, and the American West, and I find some Abbey and Stegner in this new book, both in style and content.

He looks at all these icons in the context of the modern West with a clear and analytical eye.
