The landing was the hardest part of the route; from shore the party climbed through a rocky barrier on the right side of the north face to the northwest ridge above a prominent rock spire, then followed moderate snow slopes to a summit described as a spectacular point above the big walls of the southwest face, which drop into the ocean. A second ascent followed in January 2013, while the impressive rock tower of the cape remained unclimbed.<sup>[2](https://publications.americanalpineclub.org/articles/13201212772/Cape-Perez-ca-650m-north-face-and-northwest-ridge-First-Sister-of-Fief-986m-east-face)</sup> Other ascents of the cape, a steep-faced promontory on the southern side of Collins Bay, have included one by a Brazilian team led by Joao Paulo Barbosa traveling aboard Sauvage.<sup>[4](https://publications.americanalpineclub.org/articles/13201212339)</sup>\n\n## References\n\n1.
