The first mountaineering in the area was before 1903, by a Frenchman, Georges Courty, whose notes led to the mysterious entry in the 1987 book Mountaineering in the Andes by Jill Neate, "Nuevo Mundo, 6020 m, location uncertain."[REF] .
At the end of the 1990s, Toto Aramayo, Yossi Brain and Dakin Cook undertook the search for Ahlfeld's Nuevo Mundo, and they thought they had found it at Latitude:19°47'0"S, Longitude: 66°29'0"W [REF].
