Sierras de Ambargasta, Mountain range in Santiago del Estero, Argentina.
The Sierras de Ambargasta is a mountain range in the northeastern region that rises gently above flat loess plains in a series of low ridges. The heights reach roughly 500 meters and are covered with dry vegetation and scattered woodland, creating an open terrain that is relatively easy to traverse.
These mountains were originally inhabited by settled Native American groups, the Tonocotes in the north and Sanavirones to the south, long before Spanish arrival. Their settlement patterns and way of life are witnessed through archaeological traces found across the region.
These mountains serve as a retreat for local communities who practice traditional activities like livestock herding and wood gathering in the surrounding areas. The landscape remains closely tied to agricultural rhythms and provides residents access to natural resources.
The area has a continental subtropical climate with a dry season from May through October and a wetter period from November to April. Visitors should prepare for large temperature swings between day and night and pack accordingly depending on the season.
The mountains are composed of pink granitoids with low biotite content, formed during a magmatic arc in the Early Paleozoic period. This geological makeup is relatively rare and draws the interest of scientists and geology enthusiasts visiting the region.
