In this place since the fifties two or three families lived mainly dedicated to the temporary planting of corn, beans, squash, sesame, that is to say, taking advantage of the rainy season to achieve self-consumption production and hunting of wild animals.
For the same purpose, in 1956 Messrs. Donald Brockington (archaeologist) and Gabriel de Cicco (ethnologist) sent by the MEXICO CITY COLLEGE and the ESCUELA NACIONAL DE ANTROPOLOGÍA E HISTORIA; carried out a study on the land of Mr. Luciano Cruz Ensaldo located next to the breach heading for Puerto Ángel in which figures, sherds and vessels were found, representing the Monte Albán I or II periods. Others correspond to the Tehotihuacan influence arrived perhaps through Monte Albán. Two supports were also found, one polychrome that may signify Mixtec occupation.
In short, there appears to have been a long and continuous occupation by groups of various cultural influences.
