The Deposito de Evaporación Solar "El Caracol" (also known as El Caracol de Texcoco or "El Caracol de la Ciudad de México) is a spiral-shaped land formation located to the northeast of Mexico City, in the municipio of Ecatepec de Morelos, Mexico. This Giant Spiral is located next to Central Avenue, near from the "Las Americas" Shopping Mall & Residential zone.
It was formed by the sediment of the Lago de Texcoco. It is called el caracol (the snail) for its unusual spiral shape, approximately 3,200 m in diameter. It was once used for the solar evaporation of water, to obtain sodium salts. It currently supplies water for industrial uses to the nearby regions, including parts of Mexico City.
