| 説明 | Made a stop on the way to Death Valley!The Trona Pinnacles is one of the most unusual geological features in the California Desert National Conservation Area. The unusual landscape consists of more than 500 tufa spires (porous rock formed as a deposit from springs of streams), some as high as 140 feet (43 m), rising from the bed of the Searles Lake (dry) basin. The pinnacles vary in size and shape from short and squat to tall and thin, and are composed primarily of calcium carbonate (tufa). They now sit isolated and slowly crumbling away near the south end of the valley, surrounded by many square miles of flat, dried mud and with stark mountain ranges at either side.The Pinnacles are recognizable in more than a dozen hit movies. Over thirty film projects a year are shot among the tufa pinnacles, including backdrops for car commercials and sci-fi movies and television series such as Buck Rogers, Battlestar Galactica, Star Trek V: The Final Frontier, Disney's Dinosaur, The Gate II, Lost in Space, and Planet of the Apes.However it may appear to you, a visit to the Trona Pinnacles will be a journey into one of the most unusual geologic wonders in the California Desert. These tufa spires were formed underwater 10,000 to 100,000 years ago when Searles Lake formed a link in an interconnected chain of Pleistocene lakes stretching from Mono Lake to Death Valley. |
