Rio Grande (Jujuy) in the context of "Quebrada de Humahuaca"

The Quebrada de Humahuaca is a narrow mountain valley located in the province of Jujuy in northwest Argentina, 1,649 km (1,025 mi) north of Buenos Aires (23°11′59″S 65°20′56″W / 23.19972°S 65.34889°W / -23.19972; -65.34889). It is about 155 km (96 mi) long, oriented north–south, bordered by the Altiplano in the west and north, by the Sub-Andean hills in the east, and by the warm valleys (Valles Templados) in the south.

The name quebrada (literally "broken") translates as a deep valley or ravine. It receives its name from Humahuaca, a small city of 11,000 inhabitants. The Grande River (Río Grande), which is dry in winter, flows copiously through the Quebrada in the summer.
