Dead-ice

Dead ice is the ice on a part of a glacier or ice sheet that is no longer moving. As dead ice melts in its original position, 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. Such features include kettle holes. Landscapes forming Veiki moraines in northern Sweden and Canada have been attributed to the errosion of extensive bodies of till-covered dead ice.
