Cape Horn is the southernmost headland of the Tierra del Fuego Islands in Chile. Whilst not the southernmost point of South America, it was used as a major landmark for cargo ships navigating the Drake Passage on their round-the-world trade routes. The waters are extremely dangerous due to unpredictable currents, strong winds and icebergs, and many ships foundered here. Since the opening of the Panama Canal in 1914, the need to sail round Cape Horn was made redundant, although it is still navigated by some round-the-world yacht races and recreational sailors.
