Along the east coast of the United States, the southernmost advance of this ice is recorded by the enormous sand and drift deposits of the terminal moraines that form Long Island and Cape Cod.

沿着美国东海岸，最南边的冰川运动被大量的沙子和终碛石的漂流沉积物（形成了长岛和科德角）所记录下来。

As geologists mapped glacial deposits in the late nineteenth century, they became aware that there were several layers of drift, the lower ones corresponding to earlier ice ages.

19世纪晚期，在地质学家对这些冰川沉积进行定位的时候，他们意识到有好几个漂流层，位置较低的对应的是更早的冰川期。

Once detached from the ice shelf, these bergs drift in the currents and wind systems surrounding Antarctica and can be found scattered among Antarctica's less colorful icebergs.

一旦与冰架脱离，这些冰山就会受到南极洲附近的洋流和季风系统的作用，并开始漂移。人们可以在南极洲较暗淡的冰山群中找到这些散落的冰山。
