About
The Alberca de Los Espinos or Alberca de Santa Teresa is a volcanic crater lake that is located in a state protected area that includes 142 hectares within the Mexican state of Michoacán. The body of water is located in the crater of an inactive volcano, whose highest point is located at 2,100 meters above sea level and whose maximum diameter of the crater is 740 meters, which, based on radiocarbon studies, made its last short-term duration monogenetic eruption about 25,000 years ago. The water surface is located at an altitude of 1,980 meters above sea level, has a semi-elliptical shape with a maximum diameter of 350 meters and reaches a maximum depth of 29 meters. Due to its depth, the body of water undergoes thermal stratification, which is why the nutrients of the aquatic bed are resuspended, causing the water to turn brown in cold seasons. Once the suspended nutrients are absorbed by the plankton, they increase their population, turning the water green and blue in warm seasons. In the site, which was declared a protected natural area on March 14, 2003, and a Ramsar Site on February 2, 2009, there are different species of flora, for example: Nogalillo, palo esopeta, flame coral tree, cazahuate, copal, white sapote, ceiba, white capulín, red logwood, chinquapin oak, white oak, bonpland willow, tropical ash, smooth mesquite, ahuehuete, huisache, carricillo, eucalyptus, chicas
