A small dust plume blows off mainland Mexico over Golfo de California (Gulf of California), almost reaching Baja California. Source points for that plume are not apparent in this image, but the clear skies over most of the Mexican state of Sonora indicate that the dust has arisen near the coast.
Source points do appear for the dust plumes arising from the Baja California Peninsula. Midway down the peninsula, where the dust arises, sandy desert comprises much of the landscape.
