What encounters with animals does Cheryl describe along her journey in Chapter 5: “Tracks”? What realizations do these encounters lead her to?

When Cheryl sees mountain lion tracks on the road in front of her, she begins to get afraid but her focus is taken off of the lion when she is charged by a bull. As she's overcoming these obstacles, Cheryl is realizing that the PCT is forcing her to face her fears and it's not allowing her to escape what's in front of her.
