科学家认为这些沟壑形成的最佳原因是，附近的水冰因季节性消融而形成的沙浆及液态水流下山丘形成了这些沟壑。
Scientists think the best explanation for the gullies is that seasonal melting of nearby water ice creates slurries of sand and liquid water, which flow down the crater's dunes.
通过对陨石坑的内外以及附近的观测，众多特征都显示出了富含冰质的地势，这一点为这些沟壑的“水形成假说”提供了证据。
Many of the other features observed in and around this crater are indicative of an ice-rich terrain, which may lend credence to the water formation hypothesis for these gullies.
当组件翻转使用时，地形会变得平坦，“沟壑”之上也可以形成桥梁。
When the components are flipped, the "terrain" is less rugged and "Bridges" can take shape above the gaps.
沟壑由于河流冲刷而在地球表面形成的深而窄的山谷或峡谷。
A deep, narrow valley or gorge in the earth's surface worn by running water.
在峰峦之间，沟壑、峡谷纵横，溪流、池塘和瀑布随处可见，景区内还有40多个石洞和两座天然形成的巨大石桥。
Between the peaks lie ravines and gorges with streams, pools and waterfalls, some 40 caves, and two large natural Bridges.
