evidence: In the area determined between the parallels of South Latitude 49º10'00" and 49º47'30" and the meridians of West Longitude 73º38'00" and 72º59'00", the Chile–Argentina Joint Boundary Commission must draw up a chart at a scale of 1:50,000 in order to demarcate the boundary, in that sector the Additional Specific Protocol on Shared Water Resources of 2 August 1991 will not be applied.[30] This sector corresponds to a rectangular territory that goes from a few kilometers north of the summit of Fitz Roy to Mount Murallón, in which there is an area without boundary demarcation. Within this area, however, the agreement itself demarcated the boundary from Fitz Roy to a few kilometers to the southwest (point B), and, from the same mountain to the north, it was defined by means of the 1994 Laguna del Desierto arbitration award.[31][32][25][26][33]
