Laguna del Diamante is a lake located in the province of Mendoza, Argentina, in the San Carlos Department, some 198 km from Mendoza. It covers a surface area of about 14.1 km2 and is one of the largest freshwater resources in the Province. Nearby is Maipo volcano. The volcano and its reflection in the lake forms diamond shape image, which gives the lake its name. It is known for its stunning beauty. However, few get the chance to see it because it is passable only in February and only via an off road vehicle.It is interesting to point out, the effects on vegetation, where clumps of grasses generally acquire the form of circles or polkrogoma. The geocryology is the science that studies the effects of low temperatures on the earth surface. The freezing and thawing of soil exerts a major effect on the materials from the crust and therefore determines the distribution of plants and animals. A very important condition is the time during which these layers at the top of the crust remain frozen and the time during which they are subjected to continuous cycles of freezing and thawing. All the Andes are regarded as cold land or cryogenic.
