 In summer, the wind at Cape Horn is gale force up to 5% of the time, with generally good visibility; however, in winter, gale-force winds occur up to 30% of the time, often with poor visibility.The terrain is almost entirely treeless peat and its main characteristic is the presence of tuberous vegetable formations covered in low dense Poaceaes (Gramineae), lichen and mosses that are resistant to the low temperatures and harsh weather.In some parts, small wooded areas of Antarctic beech or nire, lenga, winter's bark or canelo, and Magellanic coigüe can be found.
