Cape Horn, Chile, the southernmost point of South America. It is a high, steep promontory on Horn Island, part of the Tierra del Fuego archipelago. Sailors always have dreaded “rounding the Horn,” where the Atlantic and Pacific meet, because of the turbulent seas, icebergs, and fierce storms. The passage is avoided by taking the route through the Strait of Magellan to the north, or by using the Panama Canal. Cape Horn was discovered in 1616 by the Dutch navigator Willem Schouten and was named for Hoorn, Holland.
