Inuit families going off on snowmobiles to prepare their summer hunting camps have found themselves cut off from home by a sea of mud, following early thaws.
Because of the cold temperatures, the tundra has two layers: top layer, which is called the active layer, is frozen in the winter and spring, but thaws in the summer.
由于寒冷的气温，冻土带有两层：最上面的一层被称为活动层，在冬季和春季被冻结，但在夏季解冻。

Exhumations are to begin when the ground thaws, probably in March.
