Nevado de Chañi
Nevado de Chañi is the physical limit between the provinces of Jujuy and Salta. Many peaks higher than 5,000m are part of the group, such as the Cerro Paño (5.517 m) and Nevado del Castillo (5.565 m). The highest summit of Nevado de Chañi is named Cumbre General Belgrano. The normal route to the main summit is by the east side and is technically easy. On the south face there are challenging routes on mixed ground (D to TD) with some interesting Scottish climbing. The mountain is frequently climbed by its normal route but on the south face there have been only 5 or 6 recorded ascents as of July 2007. This mountain group is made of relatively compact granite, the only exception in the North of Argentina. Several technical routes waiting for a first ascents are located in the area.
