Sabkhas are coastal salt flats where evaporation outruns the sea
Along hot arid coasts, sabkhas form where seawater seeps into low flats and evaporates faster than it can flush, leaving crusted salt and muddy evaporites.
The surface can be soft, blindingly bright, and chemically aggressive — a harsh habitat between marine and true desert.
The ocean can lose on dry land. Sabkhas show coastal deserts are factories that turn brine into stone-hard white crusts.
