Chilean Antarctic Territory

Chilean Antarctic Territory is a region of Antarctica claimed by Chile. However, since the Antarctic Treaty came into force in 1961, most countries do not recognize territorial claims in Antarctica. It ranges from 53° West to 90° West and from the South Pole to the 60° South parallel, partially overlapping the Argentine and British Antarctic claims.

Research Stations
Chile operates four permanent bases in the territory, Base Frei, Base O'Higgins, Base Arturo Prat, and Base Prof. Julio Escudero. Five seasonal bases operate only during the summer: Estación Glaciar Unión, Base Yelcho, Base Doctor Guillermo Mann, Base Gonzalez Videla, and Base Carvajal. Chile also maintains four small shelters for occasional research or emergency purposes, Refugio Julio Ripamonti, Refugio Luis Risopatrón, Refugio General Jorge Boonen Rivera, and Refugio Collins.
