After the signing of the
1881 Treaty between Argentina and Chile, the border in the area was defined in 1899 by demarcation experts,
Francisco Pascasio Moreno from Argentina and
Diego Barros Arana from Chile. The Huemul was declared a boundary marker. The experts had no disagreements between Mount Fitz Roy and Cerro Stokes, unlike other territories that were submitted to arbitration in the
1902 award. The boundary was defined over the following mountain markers and their natural continuity:
Fitz Roy,
Torre,
Huemul,
Campana, Agassiz,
Heim,
Mayo, and
Stokes. == References ==
