Base
Eduardo Frei Montalva Station
Chile constructed this station, known as Frei station, in 1969 on the nearly ice-free Fildes Peninsula at the island’s southwestern tip, and 10 years later it added Teniente Rodolfo Marsh Martin station less than 1km across the peninsula. Frei has since incorporated Marsh, and thus the station’s name appears as either Frei or Marsh on charts. Together with the Escudero base, Frei/Marsh is one of the Peninsula region’s largest and most complex stations.
