How does John Muir use imagery in The Wild Muir: Twenty-two of John Muir's Greatest Adventures?

The imagery is very muck reflective of the natural settings Muir finds himself in. Rather than focus on himself, Muir spends nearly all of his time describing the plants, animals, and geology of the areas he explores. His descriptions are far from mundane as he gives almost spiritual descriptions of nature and deliberately seeks out beautiful scenery.
