夏日走过山间 Higher there are several small terminal moraines of residual glaciers shoved forward at right angles against the grand simple lateral of the main Tuolumne Glacier. 更高处有几个小的残余冰川终端冰碛以直角向前推进, 与图奥勒米主冰川的大单侧冰川形成直角。 优山美地 Climbing to the top of it, I discovered a very small but well-characterized glacier swooping down from the shadowy cliffs of the mountain to its terminal moraine. 爬到山顶,我发现了一条非常小但特征鲜明的冰川, 从山上阴暗的悬崖上俯冲下来, 一直延伸到末端的冰碛。 加州的群山(上) Here, also, I observed a series of small terminal moraines ranged along the south wall of the amphitheater, corresponding in size and form with the shadows cast by the highest portions. 在这里,我还观察到一系列沿着圆形剧场南墙排列的小端碛, 大小和形状与最高部分投下的阴影相对应。 加州的群山(上) Moraine Lake furnishes an equally interesting example of a basin formed wholly, or in part, by a terminal moraine dam curved across the path of a stream between two lateral moraines. 冰碛湖提供了一个同样有趣的例子,一个盆地完全或部分由一个终端冰碛坝形成,该坝弯曲穿过两个侧冰碛之间的溪流路径。 加州的群山(上) A short, ragged-edged glacier crawls into it from the south, and on the opposite side it is embanked and dammed by a series of concentric terminal moraines, made by the glacier when it entirely filled the basin. 一条短而边缘参差不齐的冰川从南面爬入其中,在它的另一侧,它被一系列同心的终端冰碛筑成堤坝,这些终端冰碛是冰川完全填满盆地时形成的。 加州的群山(上) The series of small terminal moraines which I had observed in the morning, along the south wall of the amphitheater, correspond in every way with the moraine of this glacier, and their distribution with reference to shadows was now understood. 我早上观察到的一系列小端碛,沿着圆形剧场的南墙,在各个方面都与这条冰川的冰碛相吻合,现在我们了解了它们相对于阴影的分布。
中文百科
冰碛冰碛,又称冰碛丘陵,是指任何一种冰川消融之后,在表碛内碛中的碛几乎都沉流到冰川的谷底,和底碛、中碛合称为基碛,这些冰碛沉积物随着时间流逝,跟着谷底的地形和强风,逐渐变成高低起伏的大小丘陵,因此称为冰碛丘陵。冰川越大,丘陵就越大,例如:大陆冰川。
英语百科
Terminal moraine 冰碛![]() ![]() ![]() A terminal moraine, also called end moraine, is a type of moraine that forms at the snout (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, and has been pushed by the front edge of the ice, is driven no further and instead is dumped in a heap. Because the glacier acts very much like a conveyor belt, the longer it stays in one place, the greater the amount of material that will be deposited. The moraine is left as the marking point of the terminal extent of the ice. |
