Salado River (Argentina) under the name of Juramento River at the Andes range, from thaw and captured precipitations of the high Acay and Cachi mountains in the Salta Province, near Catamarca Province. The Cabra Corral Dam regulates its flow, and deviates some of it for irrigation. When the river enters the Gran Chaco plains it forms several arms in a broad riverbed only partially occupied. The river then enters the Santiago del Estero Province from the north, near the border with the Tucumán Province, receiving the name of "Salado". The Salado and the Dulce River ("Sweet River") south to it, run diagonally in
Ojos del Salado of transverse valleys. Ojos del Salado like other major neighbouring mountains is a complex of lava domes and lava flows, with the main summit surrounded by peripheral domes such as El Solo and El Fraile and many other lateral centres. Fumaroles are encountered at the summit of Ojos del Salado within a depression. Potassium-argon dating has yielded ages of 1.2 ± 0.3 million years ago and less than 1 million years ago from rocks north of Ojos del Salado. There are glaciers on the mountain, in the crater and in the form of penitentes which reach heights of . Other
