Bowling Ball Beach
保齡球海岸
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.
位于加利福尼亞的Mendocino小鎮(zhèn)。這附近的地形被叫做Schooner Gulch，在這里你可以大飽眼福，看到聞名的“保齡球海岸”。上千塊巖石聚集在一起像個(gè)小軍團(tuán)似的抵御潮汐。奇怪的是在沒有人類干預(yù)的情況下，這些石塊兒無論是大小還是形狀都是一樣的，連間距都一樣。
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.
其實(shí)原因很簡單，地質(zhì)學(xué)上稱這些石頭為凝固石比新生成的泥石更有彈性。數(shù)百萬年來，這片海灘經(jīng)受著太平洋海水持續(xù)的侵蝕，雕琢成了這些球形石頭。
