Diego Ramírez Islands
The Diego Ramírez Islands () are a small group of subantarctic islands located in the southernmost extreme of Chile. History. The islands were first sighted on 12 February 1619 by the Spanish Garcia de Nodal expedition, and named after the cosmographer of the expedition, Diego Ramírez de Arellano. They were cited as the southernmost land mass plotted as of that time, and retained the distinction for 156 years, until the discovery of the South Sandwich Islands in 1775. In 1892, the Chilean government rented the islands to Pedro Pablo Benavides for fishing and on condition that a lighthouse , a port, and a school would be built. Later the rent was transferred to Koenigswerther and Pasinowich. The Chilean Navy established a meteorological station above Caleta Condell, a small cove on the northeastern side of Isla Gonzalo (Gonzalo Island), in 1957, and resupplies it several times each year. This is the southernmost inhabited outpost outside Antarctica. The next most southerly inhabited outpost is the lighthouse of Cape Horn. Cruise ships occasionally pass by on their way to and from Antarctica. Geography. The islands lie about west-southwest of Cape Horn and south-southeast of Ildefonso Islands, stretching north-south. They  are divided into a smaller northern group with six islets, and a larger southern group, separated by a passage wide. The two largest islands, Isla Bartolomé and Isla Gonzalo, both lie in the southern group. Águila Islet ("Islote Águila"), the southernmost land of the group, is at latitude and longitude coordinates 56°32'9"S. They lie about 350 km north of Sars Bank, a seamount that once may have been an island. Climate. The islands have a tundra climate ("ET)" with abundant precipitation. Temperatures remain chilly to cool throughout the entire year. Environment. Important Bird Area. The islands have been  designated as an Important Bird Area (IBA) by BirdLife International for their significant seabird breeding populations. These include colonies of macaroni and southern rockhopper penguins, grey-headed and black-browed albatrosses, and blue petrels.
