Cordón los Clonquis is the official name for a chain of sedimentary mountains outside Mendoza. It contains five principal summits that separate Quebrada de Chorrillos to the south from Quebrada del Potrero Escondido to the north. One of the peaks, Cerro Tito, was climbed in January 2016 and reported in AAJ 2016. Three additional summits were claimed later in 2016. Only Clonqui Oriental (4,400m) remains unclimbed, primarily because of its vertical rotten rock.
Cerro Horqueta (4,565m), at the extreme south end of the chain, was climbed in March by Glauco Muratti and Adrián Petrocelli (Argentina). They climbed the northwest face from Quebrada de Chorrillos. In the same month, the two climbers ascended the west face of Cerro Tropa (4,530m). Neither route has hard climbing, but there are some exposed steps to UIAA III. In October, Diego Molina and Pablo González (Argentina) climbed Clonqui Central (4,576m) from the Quebrada del Potrero Escondido. They reached the summit by a snow couloir with easy but exposed rock steps, ascending 1,300m from their base camp.
