MONUMENTO NATURAL ABRA DEL ACAY (ARANS)
In the area there are important extensions of high Andean wetlands and peatlands, where biodiversity is concentrated; this includes wild camelids (vicuñas and guanacos) and domestic camelids (llamas), which graze in these wetlands. Surrounded by mountain peaks and snow-capped volcanoes, the area is crossed by the well-known National Route 40, which has its highest pass precisely in the Abra del Acay (at 4950 m; the highest road pass in Argentina).
The installation of the site began in February 2011 and ended in February 2013.
It is located in the department of Los Andes, Salta, on the border between the Cordillera Oriental and the Puna (-24.43 LS, -66.23 LW). Geologically the area includes marine sediments (ordovician), schist and volcanic rocks.
