Step-by-step explanation:
The setting of the story can be determined by specific phrases that depict the time of day. Those phrases include 'the ruffled edges of the clouds had turned gold', 'reflecting the coming sunset', and 'the last time for us till we dare come again to the Utah border'. These references to the color of the clouds, the reflection of the sunset, and the direct mention of the sun setting all indicate that the events are taking place in the evening, as the day transitions into night.
