Ispa Rid, Southeast ridge, Cordillera Carabaya. Travelling by car from Santiago, a Chilean group reached the base of Allin Capac’s sister peak, at times called Ispa Riti (5723 meters, 18,776 feet). A base camp was placed at 4200 meters in the Antajahua valley and a high camp at 5200 meters on the ice. The peak was ascended via the southeast ridge by G. Cassasa, D. Delgado, G. Naccicio and A. Neira on Aug. 2, 1980, a new route. History of previous ascents to this peak is uncertain.
