Gypsum crystals are caused by saline ground water evaporating under the hot desert sun. This crust, which is known as Gypcrete, forms and often occurs where the lower parts of
the desert basins lie adjacent to dried salt lakes. Since high rainfall would dissolve any sulphates, Gypcrete can only develop in arid conditions. Tyre tracks can be an unsightly look to Gypcrete areas, so please refrain from making your own tracks as they will remain for many years.
