In the scene described from Cormac McCarthy's "Blood Meridian," the imagery evokes a vivid sunset where the sun has just disappeared. The sky is filled with red-hued clouds resembling reefs, which adds a sense of intense, raw beauty to the setting. This portrayal draws attention to the harsh environment and suggests an underlying turmoil, as if the natural world is a reflection of conflict and struggle.

The mention of desert nighthawks rising like "fugitives from some great fire at the earth's end" conveys a sense of urgency and drama. These birds serve as symbols of survival in a harsh landscape, emphasizing themes of escape and resilience against overwhelming odds. McCarthy's language creates a powerful and haunting atmosphere, inviting readers to reflect on the desolation and beauty of the world he portrays.
