Now, I wanted to see the pole it-self, and some eight hours after we met the submarine, we were crashing through that ice, surfacing, and then I was standing in an eerily beautiful snowcape, windswept and sparkling white, with the horizon defined by little hummocks, or "pressure ridges " of ice that are pushed up like tiny mountain ranges when separate sheets collide.

现在我想实地考一下北极极点。我们登上潜艇约八个小时后，潜艇冲破冰层浮上面。于是，我便置身于一片神奇瑰丽的冰雪世界中。雪原上寒风劲扫，银光闪耀，其边缘则是一道由连绵起伏的小冰丘或由冰席相撞、相互挤压而形成小型山脉的冰层"压脊"勾勒出的地平线。
