Dead ice is the ice in a part of a glacier or ice sheet that is no longer moving.[1] As the ice melts, it leaves behind a hummocky terrain known as dead-ice moraine. Dead-ice moraine is produced by the accumulation of sediments carried by glaciers that have been left behind from ice melting. Features of such terrain include kettle holes.[2][3] Landscapes forming Veiki moraines in northern Sweden and Canada have been attributed to the erosion of extensive bodies of till-covered dead ice.[4]
