Hito Esmeralda

The Hito Esmeralda (English: Emerald Landmark) is a tripoint where Argentina, Bolivia and Paraguay meet. This geographical point is at the edge of Pilcomayo River, at an altitude of 200 m (660 ft), with coordinates of 22°13′31″S 62°38′11″W / 22.22528°S 62.63639°W / -22.22528; -62.63639.

Located within the region called Gran Chaco, the boundary marker marks a triple border region in South America; It is located more precisely 8 km (5 mi) northeast of the Argentine town of Santa Victoria Este and 8 km north of La Merced Mission, both in the province of Salta.

[update] Since 14 June 2016, the Hito Esmeralda no longer is the tripoint marker. The real tripoint used to be a -so called - wet tripoint. So, at 2.650 mtr. from the wet tripoint the 'Hito Esmeralda' was placed. Due to circomstances the real tripoint became a dry tripoint, reason for placing a new (real) tripoint marker off 4,5 mtrs high on June 14th 2016.

The Chaco limit was established by Hayes Case in 1878,^[1] and by the treaty complementary to the limits of 1939 signed in Buenos Aires,^[2] and ratified in Asunción in 1945.^[3] and ratified in La Paz in 2016.^[4]
