When the sun sets in Grand Isle, La., it casts a fiery glow around the marshland. It sinks slowly, igniting long, wispy clouds. Orange light stretches along Louisiana Highway 1. The large amounts of oil stuck to the rims of the area’s thousands of marshes turn green stalks of grass into yellow kindling. Despite the abundant fuel, the ocean swallows the blood-red disc and begins to reflect the cool night sky.
