How does Wallace Stegner use imagery in All the Little Live Things?

Example of Visual Imagery:

"So I went on picking up my daily beer cans along the lane where the freedom force threw them, and every day or so I built a little bonfire on the asphalt road by the mailboxes to get rid of the throwaway newspapers, boxholder letters, free samples, and other junk mail that began finding its way to Peck, as to other mortals, the house he announced himself in residence."
