是什么造就了火星上这座不同寻常的山丘？没人能确定。在盖尔环形山中，西卡尔点从周围的环境中脱颖而出，这是一个很好的观测周围地区的视角。去年年底，好奇号火星探测车造访了这个不寻常的土丘。锡卡角不仅有独特的形状，而且在浅色岩石之上还有深色岩石。深色岩石的年龄明显要年轻得多，这表明岩层通常的地质顺序出现了时间断裂——其过程尚不清楚。火星山以地球上的西卡尔点命名，苏格兰的一个地方因两个不同岩层之间的交界处而与众不同。好奇号继续探索火星上的盖尔环形山，寻找古代生命的线索。与此同时，2300公里外，它的姊妹月球车毅力号正在探索耶泽洛陨石坑，在那里有飞行能力的侦察员独创性的协助下。

What created this unusual hill on Mars? No one is sure. A good outlook to survey the surrounding area, Siccar Point stands out from its surroundings in Gale Crater. The unusual mound was visited by the robotic Curiosity rover exploring Mars late last year. Siccar Point not only has a distinctive shape, it has dark rocks above lighter rocks. The apparent much younger age of the dark rocks indicates a time-break in the usual geological ordering of rock layers -- by a process yet unknown. The Martian hill is named for Siccar Point on Earth, a place in Scotland itself distinctive as a junction between two different rock layers. Curiosity continues to explore Gale crater on Mars, looking for clues of ancient life. Simultaneously, 2300 kilometers away, its sister rover Perseverance explores Jezero crater, there assisted by the flight-capable scout Ingenuity.
