The San Elizario Salt War was a dispute over ownership and access to these salt deposits. Alternating light and dark bands are either gypsum-rich (light) or dolomite-rich (dark) When the playa is dry during the summer, winds blow the gypsum into sand dunes. Cyanobacteria (blue-green algae) grow on the surface and immediately below the surface when the playa is wet. Capillary evaporation in the dry, hot weather pulls brine upwards and evaporite (gypsum, halite) and carbonate (calcite, dolomite) minerals precipitate. Today, a briny water table is about three feet below the surface. Originally the playa was a lake during the late Pleistocene, but drying of the climate since then has left a salt pan. The playa occupies the north-south oriented Salt Basin Grabben, which lies between the Guadalupe and Delaware Mountains on the east and the Sierra Diablo and Diablo Plateau on the west. It straddles the New Mexico-Texas border and is about 150 miles long, and 5 to 15 miles wide making it one of the largest gypsum playas in the United States.
