How quickly things can change from day to day. The stream of water is no longer flowing down the alley from the puddle. Pieces of the bottom of the puddle are lifting off and floating across the top of the puddle. The odor coming from the puddle was awful. This is why I called this photo, "Swamp Junk." The puddle smelled like a swamp. Those objects floating around must then be "swamp junk".
