What is the author's style in Desert Solitaire by Edward Abbey?

The author writes for anybody who will read his work. According to the Author's Introduction, much of the book comes directly from his journal, and thereby the prose carries flavors of conversation and informal storytelling. The reader can imagine sitting down in a Moab three-point-two bar with Abbey and listening to him spin the yarns, possibly with animated gestures and acting out situations. In places, he becomes a lecturing environmentalist, in others the sensitive observer of humanity, a sociologist without the tape recorder, camera and notepad. Abbey's style often follows his flow of consciousness and recollection, which creates another sense of being in the same room with him.
