说明: 有人认为这些酷似雉堞[4]的山峰,会保护我们免受银河[5]系中心的影响。 亦称为拉瓦雷多三尖峰[6]的三尖峰,之所以至今仍然高耸,则是因为组成它们的高密度白云岩,比周围的较软岩石更耐侵蚀[7]。 它们大约形成于2亿5000万年前[8],与地球[9]上最近一次的生物大灭绝事件[10]的年代相当。 最可信的假说认为,这次大灭绝[11]是因为大约10公里宽的小行星[12](比圣母峰[13]大)撞击地球所造成的。 数世纪以来,人类[14]不断在此仰望银河[15]系的繁星及更后方的恒星,让这些城垜般、隶属于意大利多罗迈兹山脉[16]的群峰,成为当今[17]和古天文学家[18]观星的热门地点。(merlon 雉堞、垛墙;the Three Merlons 三尖峰)
