After the signing of the
1881 Treaty between Argentina and Chile, the boundary in the area was defined in 1898 by the boundary surveyors,
Francisco Pascasio Moreno from Argentina and
Diego Barros Arana from Chile. Huemul was declared a border landmark. The surveyors had no differences in the area between Mount Fitz Roy and Cerro Stokes, unlike other territories that were subject to arbitration in the
1902 arbitral award. The boundary was defined by the following mountain landmarks and their natural continuity:
Mount Fitz Roy,
Torre, Huemul,
Campana,
Agassiz,
Heim,
Mayo, and
Stokes (nowadays Cervantes). Chile has defended it as a border landmark. In 1998, the "Agreement between the Republic of Chile and the Republic of Argentina to determine the boundary line from Mount Fitz Roy to Cerro Daudet" was signed, defining section A and a small part of section B, with the area between Fitz Roy and the Murallón still pending. == References ==
