translation.en: Now each year, as new snow lands on the glacier, it melts in the summer sun, and it forms little rivers of water on the flow along the ice, and they start to melt and bore their way down through the glacier, forming big networks of caves, sometimes going all the way down to the underlying bedrock.
translation.zh: 每年，新的雪落在冰川上。 在夏天的太阳下融化。 形成了一条小河沿冰流过。 它们一边融化，一边凿穿冰川。 形成大岩洞网。 有些部分深入到了伏基岩。
