What the chart cannot hold
What becomes visible when you follow villa las estrellas beyond the familiar map?
King George Island (95 km long) concentrates more Antarctic stations than anywhere else on the continent, including Chile's Villa Las Estrellas — the only civilian settlement with families — and the Teniente Marsh gravel airstrip. Admiralty Bay is an Antarctic Specially Managed Area rich in penguins, seals and whales. Discovered in 1819 by William Smith, it was a sealing and whaling ground before the science era.
Sighted 1819 by William Smith; sealing rush 1820s; whaling anchorages; Chilean/Argentine/Soviet stations from the 1940s–1960s; Treaty governance since 1961.
