Pumasillo (possibly from Quechuapumacougar, puma, silluclaw, "puma claw") is a mountain in the Vilcabamba mountain range in the Andes of Peru, about 5,991m (19,656ft) high[5]. Pumasillo or Sacsarayoc also refers to the whole massif. It includes the peaks Pumasillo, Sacsarayoc and Lasunayoc. It is located in the Cusco Region, La Convención Province. Its slopes are within the administrative boundaries of the Peruvian city of Santa Teresa.[6]
Pumasillo was first climbed by Mike Gravina (the son of Dorothea Gravina[11]) and Simon Clark (UK) on 26 July 1957.[4][12] Harry Carslake and John Longland (the son of Jack Longland[13]), their expedition team-mates, reached the summit two days later and so did Colin Darbyshire, Kim Meldrum and Ronnie Wathen on the following day.[14]
