In the sclerophyllous forests, the native aromas of Peumo, Quillay, Litre and Espino run through the Andes Mountains along with the Volcán River and the Maipo River. Through an initiative, this territory of rich biodiversity and geodiversity, of unique morphological processes, aspires to be recognized as a UNESCO Global Geopark. The region is house of "No Alto Maipo", a social and environmental movement, that tried to stop the construction of the Alto Maipo Hydropower Plant since 2007. Owned by the US-American company AES Gener S.A., the construction was completed in 2021 with 74 km of tunnels to divert the riverbed and generate energy.
