Sierra de las Cruces
The Sierra de las Cruces, also popularly called Sierra del Monte de las Cruces, is a mountain range in Mexico, in its south central region, which delimits the valleys of Mexico and Cuautitlán in the Basin of Mexico, with Toluca Valley as well as a part of the Lerma Basin. The Battle of Monte de las Cruces took place in this mountain range, as well as the construction of the Cutzamala System.
It is part of the Transversal Volcanic Axis, and represents the watershed of three hydrological basins: the Lerma River, the Valley of Mexico (both of the endorheic type) and the Balsas River (of the exorheic type).
