There’s maybe a bit of confusion about the several names of Union Glacier Stations and Camps in Antarctica. Today we are visiting the Chilean one.
The Unión Glacier, located at 79º 46’ South, 83º 24’ West, is a large glacier converted since 2014 into the Base Camp.
Chile has long had an interest in this part of Antarctica and the Union Glacier Camp (picture aside) has became a Scientific Polar Station jointly operated by the Chilean National Antarctic Institute (INACH) and the Armed Forces who provide logistic support for the Chilean Antarctic programs.
Here is as bit of history:
In 2013 during the 68th Chilean Antarctic Campaign (ECA 50), the Polar Stations Arturo Parodi Alister (WAP CHL-14) –Picture here on the Right shows the entrance of Arturo Parodi Alister Base – established at Patriot Hills in 1996, and Antonio Huneeus Gana, were dismantled. Their equipments moved to the corridors of the future station, the Unión Glacier joint scientific polar station.
In January 2014, Chilean President Sebastián Piñera inaugurated the new Chilean Station at Union Glacier, named Estación Polar Científica Conjunta Glaciar Unión or Union Glacier Camp (WAP CHL-NEW). See picture above.
Antonio Huneeus Gana Station (WAP CHL-15): 
Picture aside is the QSL of Adam K2ARB operating from Antonio Hunneus Gana Station on last 2009).
In November 1997, the first facilities to support scientific research were carried out according to special tents. By Exempt Resolution No. 303 of October 11, 1999, it was officially named Antonio Huneeus Gana Summer Base (aka semi-permanent Antarctic camp) in memory of the Minister of Foreign Affairs of the early twentieth century, who at that time had an outstanding performance in the claim of Chilean sovereignty over the so-called Chilean Antarctic Territory. It was located 1 km from the private Patriot Hills Base Camp (WAP MNB-Ø2) of the enterprise Adventure Network International at 80°18’ 07” South, 81°20’ 39” West .
Next time we’ll see few others on the area trying to under stand their evolution.
