A stack is a geological Landform consisting of a steep and often vertical column or columns of rock in the sea near a coast Together, the Desventuradas Islands have a surface area of only 3. 9 km². The topography is very rugged, with peak elevations of 193 m on Isla San Félix, 479 m on Isla (de) San Ambrosio, 173 m on Islote/Isla Gonzalez and 53 m on Roca Catedral.

There are no permanent sources of fresh water on the islands. Vertebrates inhabiting both islands are exclusively limited to birds. Ten species of marine birds and one land bird species, some of them endangered, make their nests on or visit the islands.
Because of their isolation and difficulty of access, there are no human settlements on these islands, but a detachment of the Chilean Navy is stationed on Isla San Félix, which also hosts a 2,000 meter runway. The Chilean Navy (Armada de Chile is the naval force of Chile.
The islands were sighted by Juan Fernández in 1574, and perhaps earlier by Ferdinand Magellan in 1520. Juan Fernández (c 1536 &ndash c 1604 was a Spanish explorer and navigator Ferdinand Magellan (Fernão de Magalhães fɨɾˈnɐ̃ũ dɨ mɐgɐˈʎɐ̃ĩʃ Fernando de Magallanes (Spring 1480 &ndash April 27 1521 Mactan Island, Cebu Pedro Sarmiento de Gamboa wrote in 1579 that "they are now called after St Felix and St Ambor [i. Pedro Sarmiento de Gamboa (1532 - 1592 was a Spanish explorer author historian astronomer scientist and humanist e. Felix and Nabor])". Saints Nabor and Felix were martyred during the reign of Emperor Diocletian in 303 However, by linguistic corruption, the name of the martyr Ambor (Nabor) became confused with that of the more famous bishop Saint Ambrose (San Ambrosio). The term martyr ( Greek μάρτυς martys "witness" is most commonly used today to describe an individual who sacrifices their life (or personal freedom Saint Ambrose (c 338 &ndash 4 April 397) was a bishop of Milan who became one of the most influential ecclesiastical figures of the fourth century
