glaciation

These changes alter the intensity of sunlight hitting the Earth at high latitudes, and so affect the extent of glaciation.

这些变化改变了高纬度区域的日照强度，由此影响了冰河作用的范围。

Besides the Bow Valley, evidence of glaciation also appears in this image south of the lake, in the amphitheater-shaped cirque.

除了被迷你汪卡湖占据的弓河谷外，冰川作用的证据还可以在南部的圆形冰斗处找到。
