Between 30,000 feet (9,100 m) and 40,000 feet (12,000 m) below the surface is a layer of salt the primary source of salt domes which dot the metropolitan area. Since salt is more buoyant than other sediments it rises to the surface creating domes and anticlines and causing subsidence due to its removal from its original strata. These structures manage to capture oil and gas as it percolates through the subsurface; Pierce Junction is a notable example of a heavily drilled salt dome oil field in Houston.
