Waves of up to eight feet (2.5 metres) will roll 60 to 100 yards down a big salt-water pool.───8英尺(2.5米)的海浪可以沿着海水池推进60到100码。

The streaks range from 0.5 yards to 5 yards wide and stretch hundreds of feet, far smaller than previously detected gullies.───这些条纹有0.5码到5码宽，数百英尺长，比之前观测到的冲击峡谷要小得多。

The liquid will squeeze into tiny pores in the rock, displacing the salty water there, and assume a shape something like a squashed football, 30 to 40 feet high and hundreds of yards long.───这些流体将继续被压入地下岩石的微小缝隙中去，并取代原先在那儿的盐水。 被挤压的流体在地下会呈现出一个类似被压扁的足球的形状，大约有30至40英尺高，数百米长。
