 The San Lorenzo range is known for its high peaks, such as the San Isidro peak, which serves as a buttress in this chain of the mountains.The Velardeña valley and its rich mineral mines serve as the town limit for the village of the same name.In the northeastern part of the town, a little beyond the San Lorenzo mountains, up the steep and rugged Sierra de Guadalupe that runs parallel to the Sierra de Jimulco, in the Municipality of Simon Bolivar and the Coahuila State, the two mountain ranges of Guadalupe and Jimulco form a more or less wide canyon where the Aguanaval river and the Central railroad run.
