Third of four: Dust at El Mirage (CA desert) collected behind the first curve on the decklid, on all level surfaces on the name-plates, and the top of the bumper cover revealing the aft recirculation zone. Notice how little dust is on top of the decklid. The lack of dust on window and decklid top suggests that not much of the air from behind the car (full of turbulent dust) circulates up to the window.
