Jason Islands

The Jason Islands (Spanish: Islas Sebaldes) are an archipelago in the Falkland Islands, lying to the far north-west of West Falkland. Three of the islands, Steeple Jason, Grand Jason and Clarke's Islet, are private nature reserves owned by the Wildlife Conservation Society of New York City. Other islands in the group are National Nature Reserves owned by the Falkland Islands Government.

The islands include Steeple Island, Grand Island, Elephant Island, Flat Island and South Island.

The Spanish name for the archipelago is Islas Sebaldes; however, this is sometimes subdivided into "Islas los Salvajes" (western, Grand Jason, and Steeple Jason) and "Islas las Llaves" (eastern, Flat Jason, Seal Rocks and North Fur Island),. No such distinction exists in English-language toponymy.

The Jason Islands are somewhat geologically distinct, described by Ian Strange as "sharply rising peaks give them a grandeur found in few other areas of the archipelago".

An archipelago in the region of the Falkland Islands appeared on maps from the early 16th century, suggesting they may have been sighted by Ferdinand Magellan or another expedition of the 16th century. Amerigo Vespucci is believed to have sighted the islands in 1502, but did not name them. Both explorers were in Spanish service. In 1519 or 1520, Esteban Gómez of the "San Antonio", one of Magellan's captains, deserted Magellan and encountered several islands, which members of his crew called "Islas de Sansón y de los Patos" ("Islands of Samson and the Ducks"). Although these islands were probably the Jason Islands, the names "Islas de Sansón" (or "San Antón," "San Son," and "Ascensión") were used for the Falklands as a whole on Spanish maps during this period.
