South America, Argentina, Central Andes, Monte Pissis, Attempt, and Possible First Ascent

Monte Pissis, Attempt, and Possible First Ascent. In April, I made a solo attempt on Pissis (6759m) via the route first pioneered by Greg Home and Fritz Radun (documented by Home in the 1996 AAJ). Later, an attractive alternative summit—the western peak of the Pissis summits—presented itself to the south-southwest. This was ascended. No cairns or other markers were found on this summit. I estimate its height at 21,650 to 21,850 feet. I believe this to be a possible first ascent of this peak and also the first solo ascent.
