How does Sally's mood correspond to the setting in "The Ice Palace"?

Sally is easy, soft, comfortable, and languid in her warm, sleepy, and familiar Southern setting. She feels at home amid this warmth but has ambitions to see more of the world.
However, when she travels north to see her fiance, Harry, everything is cold and icy. Her mood corresponds to the setting because it too turns icy: she does not feel at home or comfortable in this new environment. She feels cold around the people who seem chilly and distant to her.
For example, when she arrives, Harry turns an "icy-cold" face to her. At the story's climax, she gets lost while visiting an ice palace, a labyrinth-like structure built of ice blocks. At this point, the visions and ghosts she experiences—as well as being in this cold setting—are mirrors of her alienated mood. The ice palace simply crystallizes (no pun intended) how lost, cold, and unhomelike the north is for her, and she demands to go back south.
