Ojos de San Pedro

The Río Pedro de Inacaliri is a river in the Atacama Desert in Chile , in the Región de Antofagasta . It has a length of 76 kilometers and flows largely in a westerly direction.

description

The river rises under the name Cajón in the western cordillera of the Chilean Andes , a few kilometers north of the Cerro de Colana from one of the rubble compartments of the northwest ridge of the Cordillera Occidental . As an endorheic body of water, it first flows about ten kilometers west and then another ten kilometers south, where it joins the Río Silala . Shortly after the merging of the two rivers, part of the river water, between 50 and 60 l / s, is diverted to the open copper mine in Chuquicamata , so that the river seeps into the river plain over the next eight kilometers and only another seven kilometers downstream into the so-called Ojos del San Pedro partially resurfaces. Further to the west, south of the San Pedro volcano, the river has dug itself up to a hundred meters deep into a 5 km² salt pan before it flows into the Río Loa west of the town of San Pedro .
