River Valley High

Despite the caves' perches, high above the river valley, the treasures inside are at risk from looters and souvenir collectors, as well as erosion, earthquakes, and infrequent but torrential rains.

尽管洞窟位于河谷上方的高地，但其中的宝藏还是会遭受来自抢劫者、纪念收藏家的损坏，以及侵蚀、地震和罕见的暴雨的威胁。

In each case, the glacier surged as much as two kilometers down the valley and blocked the Abdukagor River with ice DAMS as much as 100 meters high.

每一次冰川都顺着山谷向前冲击了大约2千米，冲击所形成的冰块大坝阻塞了Abdukagor河，使其标高达到100米之高。

These river valley areas, which are seasonally flooded, or have high water tables for a large part of the year, are an important dry season farmland.

这些河谷地带常发生季节性洪水，在一年的大部分时间内均保持较高的水位，是旱季重要的农田。
