Walk two moons - setting

This story "Walk Two Moons" by Sharon Creech, is anstory about a girl who is in search of her long lost mother but on the way she tells a story that is much like a parellel world to her real life.
Salamanca lost her mother long ago when she was young.this part of the story takes place in a valley full of lush green grass and a hollow tree filled with leaves. Salamanca describes the place as heavenly. This apparently reminded Salamanca of her mother. This setting represented a memory that sal had of her mother before she was gone. She says that her mother would just love the grass and trees and flowers and it connected her to nature.
Not only did this connect Salamancas mother to nature but it also connected Salamanca to nature and this is what united them both together.
I think that the author chose this setting for this part of the story because it is symbolic to Sal's mother. It represents her and relates very much to her personality. I think this is also why Sal chose this place to describe her mother and remember her. I think that everything about this story is symbolic and the way that the stories that Salamanca tells about a girl named phoebe, her life resembles Sal's real life. Everything that is described in Sal's stories are always described in detail of the setting. Salamanca's travel with her grandparents and them getting lost, may represent how her grandparents minds get lost and are constantly unfocused when it comes to getting to their final destination. It think that an example of this would be the twisted turny roads that worry Sal but not her grandparents. This can also represent their personalities. This says that oddly, her gram and gramps are more open minded and loose while Sal is more conscious and stubborn.
