The photo above shows a twilight view of "El Gualicho," the largest salt flats (in volume) in Argentina. These salt flats are located along the South Atlantic Ocean, in the Rio Negro province. The crusted salt here is approximately 23-26 ft (7-8 m) thick and lies over the uppermost soil layer, which sits about 230 ft (70 m) below sea level. Its reddish color is attributed to the brine shrimp (Artemia) that inhabit this portion of the coast. Note that the tire marks extending toward the horizon are from a salt-harvesting truck.
