About two million years ago, a hyper-saline body of water became trapped beneath Taylor Glacier, isolated from light, oxygen and heat. As the saltwater trickles through a fissure in the glacier, it reacts with the oxygen in the air to create this spectacular, rust-hued cascade.
大约两百万年前,一股含盐度极高的湖水被困在泰勒冰川下,与阳光、氧气和热量隔绝。当这股盐水流经一条冰川裂缝时,盐水与空气中的氧气反应形成这片壮观的红锈瀑布。
It’s a visual and scientific wonder, and Taylor Glacier – accessible only by helicopter from McMurdo Station or Scott Base, or cruise ship in the Ross Sea – is the only spot on Earth to see it.
这既是视觉饕餮也是科学奇观,而地球上只有在泰勒冰川——也就是从麦克默多站或者斯科特站乘直升机或在罗斯海乘游艇——才能看到这一景观。

When visitors stumbled upon scores of heavy stones that appeared to have moved across the dried lake bed of Racetrack Playa in California’s Death Valley National Park, leaving a tell-tale trail in their wake, scientists were baffled. How had so many boulders, some weighing 300kg, moved as much as 250m across this remote part of the valley, asks Quora user Farhana Khanum?
在加利福尼亚死亡谷国家公园,游客无意中发现几十块大石头在赛马场盐湖的干湖床上移动,留下神秘的尾波,科学家们也不知道如何解释这一现象。Quora用户法尔哈纳•哈姆问道,这些卵石中有的重达300千克,它们是怎么做到移动近250米到达峡谷的另一头?
