Revised Heights, Corrections and Ascents in the Pissis, Bonete and Ojos del Salado Area. An unpublished map of the Institute Geografico Militar Argentino (all the heights have been taken from here) officially gives the new height of Cerro Bertrand as 5207 meters; Cerro Peñas Azules, 5935 meters; Ojos, 6879 meters; and Cerro Nagimiento de Jagüé, 5829 meters. Ojos de Salado has been measured at 6864 meters, remaining the third highest summit on the continent, the second highest volcano on earth and the highest active volcano of the world. On November 18, 1994, in a joint expedition of the Club Andinista Mendoza, Federation Espanola de Montan and Ejercito, Laura Junrez became the first female to climb Pissis. On page 202, AAJ 1995, Pissis coordinates are given as 27° 45’ 17” S and 68° 45’ 56” W. There must be an error because the same person, Mr. Aarseth, gave in another journal the coordinates of Pissis as 27° 45’ 17” S and 68° 47’ 56” W, matching these last ones with the position of Pissis in Argentine maps. The summit stated as circa 6446 meters may be the one marked as 6504 meters in Argentine maps.
