In December 2015, Marissa Bieger and Marcelo Mascareño made the first known ascent of Cerro Cremilda (1,980m), the northern point of a chain of rocky spires northwest of Monte San Lorenzo. They approached via old horse trails, following the river valley to the south of the peak, and estab- lished a high camp on moraine below the mountain. The climb followed steep snow on the south face, a mixed gully, and sections of exposed fifth-class rock on the southwest ridge (580m, 5.3 60°). They named the tower in honor of a settler of the region, Cremilda de la Cruz.
