Please generate a brief description of a spooky scene outside a town wall with piles of sand and a towering wall.

Stinking piles line the narrow passage, obviously not intended for public use, let alone at night. Not subdued by the lack of the sun's heat, the stench forces passersby to squeeze up against the towering wall, presumably on the northwestern side of the city due to its height. Sand sprinkles down from unseen locations above the cliff opposite the wall, likely kicked up by the howling desert wind.
