世界真奇妙:十大神奇海岸之第1弹

Bowling Ball Beach

保龄球海岸

On the Californian coast is a town called Mendocino. Nearby is a coastal feature called Schooner Gulch, and this is where you can feast your eyes on what has become known as the 'Bowling Ball Beach'. Thousands of rocks appear to have gathered together to defy the tides like an army of small boulders. The weird thing is that these boulders are uniform in size and shape, as well as in their spacing, though man has nothing to do with it.

位于加利福尼亚的Mendocino小镇。这附近的地形被叫做Schooner Gulch，在这里你可以大饱眼福，看到闻名的“保龄球海岸”。上千块岩石聚集在一起像个小军团似的抵御潮汐。奇怪的是在没有人类干预的情况下，这些石块儿无论是大小还是形状都是一样的，连间距都一样。

The explanation is simple and purely geological in nature. Technically called concretions, these hard spheres are composed of materials far more resilient than the Cenozoic mudstone that once surrounded them. Over millions of years, this has eroded away under the constant onslaught of the Pacific Ocean, leaving the tougher 'bowling balls' behind.

其实原因很简单，地质学上称这些石头为凝固石比新生成的泥石更有弹性。数百万年来，这片海滩经受着太平洋海水持续的侵蚀，雕琢成了这些球形石头。
