Pre-columbian archaeological remains have been found in the reserve such as: human-made terraces, cave paintings, tombs and pieces of pottery. Archaeologists have determined the occupation of Lomas de Lachay, at least seven times, corresponding to initially hunting and gathering populations until reaching the current shepherds, also called "chivateros". There is evidence of the presence of populations influenced by the Chavín Culture (2800 years BC) from the remains of ceramics and buildings found. Likewise, there are remains of tombs that show the presence of the Tiahuanaco Culture, to be exact, between 2500 BC, corresponding to the Theatine period. The hills also suffered the influence of other great regional cultures such as the Mochica, Chimú and Chancay, to finally be subjected to the Inca Empire. During the colony, the hills were gradually vacated due to the degradation they suffered as a result of
overgrazing produced by cattle from Europe. In subsequent historical periods, the hills were deteriorating even more, due to the felling of trees as a source of energy, so that the capacity to support cattle was reduced and this resulted in the sporadic presence of settlers. == Recreation ==
