Estancia El Rincón, situated at the base of Cerro San Lorenzo, with a 12,000-foot ice-and-rock wall that looms above the property, is in the process of being donated to National Parks of Argentina. The Estancia safeguards forests of indigenous lenga and ñire trees. Grazing stopped 14 years ago and there has been a significant recovery of native grasses. Both grasslands and forest are home to a variety of fauna including pumas, upland geese, Andean condors, pink flamingos and huemul deer. In concert with the national park system and leading conservation biologists, Conservacion Patagonica is working towards eventual transfer of this property to enlarge the adjacent Perito Moreno National Park.
