In making the ascent in June or October the glacier is easily crossed, for then its snow mantle is smooth or mostly melted off.

在 6 月或 10 月攀登时，冰川很容易穿越，因为那时它的雪地幔是光滑的或大部分融化了。

Our roots, they explained, reach far down the joints of the summer-warmed rocks, and beneath our fine snow mantle killing frosts cannot reach us, while we sleep away the dark half of the year dreaming of spring.

我们的根深植于夏季温暖的岩石缝隙之下， 在我们细密的雪地幔下， 致命的霜冻无法触及我们， 而我们却梦想着春天度过了一年中黑暗的下半年。
