Laguna Salada is a vast dry lake some 10 meters below sea level (sometimes wet - sometimes dry) in the Sonoran Desert of Baja California, 30 km (19 mi) southwest of Mexicali. The lake's shape vaguely resembles a rhombus. When dry, the flatness of the exposed lake bed sediments makes it a favoured location for recreational driving. It is also notorious for its dust storms (when dry), usually the result of monsoonal thunderstorms during the summer. During times of significant rain the lagoon can fill completely with water, leaving the unpaved road along its west bank as the only means of traversing the area.
