Step-by-step explanation:
The passage provided does not include the direct thoughts of Cathy or the narrator about what the cracks in the frozen puddle looked like.
However, from the various extracts, we can discern a focus on the harshness of winter and the impact of cold, with references to the difficulties encountered by characters in frigid conditions, such as frostbitten cheeks, the deceptive dangers of spring-fed ice-covered pools on a creek, and a changing environment as observed through the change of seasons.
In the given passage, there is no mention of Cathy or the narrator observing cracks in a frozen puddle. The passage mainly focuses on different aspects such as the extreme cold weather, the man's observations of the surroundings, and his journey to a campsite. Therefore, neither Cathy nor the narrator thought about the cracks in a frozen puddle.
