Rafting was a luxury after crossing previous rivers on foot, running the risk of hypothermia or even drowning. 筏运曾经是一种奢华的方式比起过河时用脚的时代,筏运的风险在降低体温或是溺死。
Icerafting deposits are formed by the melting of sedimentladen ice blocks, which is transported into sea or lake when spring is changing into summer. 冰筏沉积是负载沉积物的冰块在春夏之交筏运到海洋或湖泊中,冰块融化沉积物坠落所形成的。
