- was a towering wall of ice.
只有一堵高耸的冰墙 - On the far side, the wall was almost a kilometer high...
在远端 这堵墙有近1000米高 - ...a seemingly unstoppable barrier...
似乎坚不可摧的屏障 - but not for much longer.
但坚持不了多久 - As temperatures kept rising and the meltwater lake kept growing,
随着温度不断升高 融水湖不断扩大 - the pressure from behind increased.
来自后方的压力增加 - Before long, the walls started to crumble from the inside out...
不久之后 墙开始从内部碎裂
