The Etosha pan, in the Etosha National Park in Namibia, is another prominent example of a salt pan. The Salar de Uyuni in Bolivia is the largest salt pan in the world. As of 2024, with an estimated 23 million tons , Bolivia holds about 22% of the world's known lithium resources (105 million tons); most of those are in the Salar de Uyuni. [ 3 ]
If its basin is primarily salt, then a dry lake bed is called a salt pan, pan, or salt flat (the latter being a remnant of a salt lake). Hardpan is the dry terminus of an internally drained basin in a dry climate, a designation typically used in the Great Basin of the western United States.

Salt marsh showing salt pannes and ponds, spartina alternifolia and invasive phragmites communis in foreground. Brackish marsh panne variants occur in brackish marshes (short graminoid variant), one of the native dominant species is spike grass (Distichlis spicata), some brackish marsh pannes are dominated by the narrow-leaved cattail (Typha angustifolia) an invasive exotic species.
Salt pans are shallow and open, and metal pans are often used to evaporate brine. They are usually found close to the source of the salt. For example, pans used in the solar evaporation of salt from seawater are usually found on the coast, while those used to extract salt from solution-mined brine will be found near the brine shaft.
The largest individual pan is about 1,900 sq mi (4,921.0 km 2). In comparison, Salar de Uyuni in Bolivia is a single salt flat of 4,100 sq mi (10,619.0 km 2), rarely has much water, and is generally claimed to be the world's largest salt pan. A dry, salty, clay crust most of the year, the pans are seasonally covered with water and grass, and ...
Salt pans can refer to: Salt pan (geology), a flat expanse of ground covered with salt and other minerals, usually found in deserts Sabkha, a phonetic translation of the Arabic word for a salt pan (geology) Salt evaporation pond, a method of producing salt by evaporating brine
The salt flats of Abu Dhabi are a typical example of this, with the evaporation of water occurring from the capillary fringe - a subsurface layer where groundwater seeps up from a water table - which intersects the surface. This activity has contributed to the creation of an expansive salt flat, covering approximately 36,000 square kilometers.
When the basin is flooded, some of the salt is dissolved; it is redeposited as clean crystals when the water evaporates. [7] A popular site for tourists is the sign marking "sea level" on the cliff above the Badwater Basin. [8] [9] Similar to Owens Lake, it is characterized by a deep bed of unconsolidated valley fill from which the salt crust ...
