How does the author use foreshadowing in Legends of the Fall?

Chapter Two provides several back-stories that give Nordstrom's character more depth. The crows have special significance to Nordstrom and foreshadow later events. He is trying to find himself and doesn't know who or what he knows or loves anymore..... or if he ever did. Getting lost after visiting his father's corpse at the funeral home is symbolic of Nordstrom's inner lack of direction. His ruined suit and shoes symbolize the lack of interest he now has in government and business. This foreshadows his change coming in the next two chapters.
